For each pair of points, find the slope of the line that passes through both points. If you get stuck, try plotting the points on graph paper and drawing the line through them with a ruler. Use fractions, not decimals, and make sure to simplify all fractions.
Answer:
a. 1 1/2 (or 3/2)
b. 2/3
c. 1
d. 1
Step-by-step explanation:
Part A: (1,1) (7,5)
To determine the slope, you will use the equation m=(y2-y1)/(x2-x1). Keep in mind that it doesn't matter what point you use for (x1, y1) or (x2, y2).
Let's plug in the numbers for part a:
m=(7-1)/(5-1)
Let's then solve the problems inside the parentheses:
m=6/4
And finally, we simplify:
m=3/2 (or 1 1/2 depending on what your teacher wants for an answer)
For these others, I will just go through the steps and not explain them, if you need help or don't understand something I'm doing, either look back at what I did for part a or comment on this answer.
Part B: (1,1) (5,7)
m=(5-1)/(7-1)
m=(4/6)
m=2/3
Part C: (2,5) (-1,2)
m=(-1-2)/(2-5)
m=(-3/-3)
m=1
Part D: (2,5) (-7,-4)
m=(-7-2)/(-4-5)
m=(-9/-9)
m=1

Answer:
First option
Step-by-step explanation:
The sign inadvertently shows you where the line should be pointing because it looks like an arrow. Not to mention it means greater than or equal to, so it would be a closed dot.

(4,5)
b. What is the equation of line j?
710
m
(5.2)
2-
109
(-3,-1)
a. The equation of line k in slope-intercept form is
(Use integers or fractions for any numbers in the equation. Simplify your answer.)
a) The equation of line k is:
[tex]y = -\frac{202}{167}x + \frac{598}{167}[/tex]
b) The equation of line j is:
[tex]y = \frac{167}{202}x + \frac{1546}{202}[/tex]
The equation of a line, in slope-intercept formula, is given by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change.b is the y-intercept, which is the value of y when x = 0.Item a:
Line k intersects line m with an angle of 109º, thus:[tex]\tan{109^{\circ}} = \frac{m_2 - m_1}{1 + m_1m_2}[/tex]
In which [tex]m_1[/tex] and [tex]m_2[/tex] are the slopes of k and m.
Line k goes through points (-3,-1) and (5,2), thus, it's slope is:[tex]m_1 = \frac{2 - (-1)}{5 - (-3)} = \frac{3}{8}[/tex]
The tangent of 109 degrees is [tex]\tan{109^{\circ}} = -\frac{29}{10}[/tex]Thus, the slope of line m is found solving the following equation:[tex]\tan{109^{\circ}} = \frac{m_2 - m_1}{1 + m_1m_2}[/tex]
[tex]-\frac{29}{10} = \frac{m_2 - \frac{3}{8}}{1 + \frac{3}{8}m_2}[/tex]
[tex]m_2 - \frac{3}{8} = -\frac{29}{10} - \frac{87}{80}m_2[/tex]
[tex]m_2 + \frac{87}{80}m_2 = -\frac{29}{10} + \frac{3}{8}[/tex]
[tex]\frac{167m_2}{80} = \frac{-202}{80}[/tex]
[tex]m_2 = -\frac{202}{167}[/tex]
Thus:
[tex]y = -\frac{202}{167}x + b[/tex]
It goes through point (-2,6), that is, when [tex]x = -2, y = 6[/tex], and this is used to find b.
[tex]y = -\frac{202}{167}x + b[/tex]
[tex]6 = -\frac{202}{167}(-2) + b[/tex]
[tex]b = 6 - \frac{404}{167}[/tex]
[tex]b = \frac{6(167)-404}{167}[/tex]
[tex]b = \frac{598}{167}[/tex]
Thus. the equation of line k, in slope-intercept formula, is:
[tex]y = -\frac{202}{167}x + \frac{598}{167}[/tex]
Item b:
Lines j and k intersect at an angle of 90º, thus they are perpendicular, which means that the multiplication of their slopes is -1.Thus, the slope of line j is:
[tex]-\frac{202}{167}m = -1[/tex]
[tex]m = \frac{167}{202}[/tex]
Then
[tex]y = \frac{167}{202}x + b[/tex]
Also goes through point (-2,6), thus:
[tex]6 = \frac{167}{202}(-2) + b[/tex]
[tex]b = \frac{(2)167 + 202(6)}{202}[/tex]
[tex]b = \frac{1546}{202}[/tex]
The equation of line j is:
[tex]y = \frac{167}{202}x + \frac{1546}{202}[/tex]

18. A shipwreck is 300 meters away from a diving station. An undersea
explorer travels away from the station at a speed of 2 meters per second.
The explorer is x meters away from the station and will reach the
shipwreck in 100 seconds. What is the value of x?
Answer:
me too jaja
Step-by-step explanation:
The value of x is 100 meters if the shipwreck is 300 meters away from a diving station. An undersea explorer travels away from the station at a speed of 2 meters per second.
What is the distance?Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
It is given that:
A shipwreck is 300 meters away from a diving station.
An undersea explorer travels away from the station at a speed of 2 meters per second.
The explorer is x meters away from the station and will reach the
shipwreck in 100 seconds.
As we know,
Distance = time×speed
Distance = 100×2
Distance = 200 meterse
x = 300 - 200
x = 100 meters
Thus, the value of x is 100 meters if the shipwreck is 300 meters away from a diving station. An undersea explorer travels away from the station at a speed of 2 meters per second.

Step-by-step explanation:
- Volume small box = 218 in^3
- Area face medium box = 49 in^2. (7x7=49)
Volume medium box = 7^3 = 343 in3
- Combine volume of the 3 boxes = 1,197 in^3

Answer:
100 marks have been obtained in the hindi subject.
Step-by-step explanation:
First you have to find how many marks are obtained by one degree. So you have:
450marks/360°=1.25marks/degree
Then you have to find how many marks are obtained for each subject.
1.25marks/degree×80°= 100 marks
1.25×72= 90 marks
1.25×70= 87.5 marks
1.25×90= 112.5 marks
1.25×48= 60 marks
100+90+87.5+112.5+60=450 marks

Answer:
Step-by-step explanation:
For number 8, to start,:
[tex]\frac{x}{4}[/tex] - 1 = 1
the first step is to add 1 to both sides of the equation; then, simplify.
[tex]\frac{x}{4}[/tex] - 1 = 1
+1 +1
----------------
next, the -1 and +1 will cancel.
[tex]\frac{x}{4}[/tex] = 2
the last step is to multiply both sides of the equation by 4.
4 · [tex]\frac{x}{4}[/tex] = 2 · 4
simplify; the 4s cancel out on the left side.
x = 8
**************************************************
For number 9, :
9 = 6 + [tex]\frac{x}{7}[/tex]
like in number 8, the first step is to subtract 6 from both sides of the equation; also, a helpful tip you can use is move the 9 to the right side; speaking personally, it often helps make things visually easier to work out. you would then rewrite the equation like: 6 + [tex]\frac{x}{7}[/tex] = 9
6 + [tex]\frac{x}{7}[/tex] = 9
now, we'd subtract 6 from both sides.
6 + [tex]\frac{x}{7}[/tex] = 9
-6 -6
-----------------
next, the 6 and -6 will cancel.
[tex]\frac{x}{7}[/tex] = 3
the last step is to multiply both sides of the equation by 7.
7 · [tex]\frac{x}{7}[/tex] = 3 · 7
simplify; the 7s cancel out on the left side.
x = 21
The area of a square is 676 square root. what is the perimeter of the square?
Answer:
the perimeter of the square is 104
Step-by-step explanation:
to find the perimeter of a square we need to use the formula P = 4a
P is perimeter and a is the side of the square
if a is the side and the formula of Area is A = a^2
that means the side of the square is a = 26 because 26 * 26 = 676
now we take 26 and place it in the a spot of the perimeter formula
P = 4 * 26 (P = 104)
