Write the equation of the line through (2,4) with a slope of 2/3 in Point Slope Form
Answer:
y - 4 = 2/3(x - 2)
Step-by-step explanation:
The format for point-slope form is: y - y₁ = m(x - x₁)
where m is the slope, x₁ is the x-coordinate and y₁ is the y-coordinate.
In (2,4), 2 is the x-coordinate and 4 is the y-coordinate.
The slope is 2/3.
When you plug in the values, you get:
y - 4 = 2/3(x - 2)

4x - 2(x - 4) = -8 + 4x +4
solve the equation please
Answer:
X=6
Step-by-step explanation:
First distribute
ie: 4x-2x+8=-8+4x+4
Next combine like terms
ie: 2x+8=-4+4x
Next subtract 2x from each side and add 4 to each side
ie: 12=2x
Then divide 2 from each side to get x alone
ie: 6=x
Your friend first multiplies each side of 1/2 (x-9)=3/4 (5x+1) by 4 when solving the equation. Why might your friend do this?
Answer:
x = (-39)/11
Step-by-step explanation:
Solve for x:
x - 9 = (3 (5 x + 1))/4
Multiply both sides by 4:
4 (x - 9) = (4×3 (5 x + 1))/4
(4×3 (5 x + 1))/4 = 4/4×3 (5 x + 1) = 3 (5 x + 1):
4 (x - 9) = (3 (5 x + 1))
Expand out terms of the left hand side:
(4 x - 36) = 3 (5 x + 1)
Expand out terms of the right hand side:
4 x - 36 = (15 x + 3)
Subtract 15 x from both sides:
(4 x - 15 x) - 36 = (15 x - 15 x) + 3
4 x - 15 x = -11 x:
-11 x - 36 = (15 x - 15 x) + 3
15 x - 15 x = 0:
-11 x - 36 = 3
Add 36 to both sides:
(36 - 36) - 11 x = 36 + 3
36 - 36 = 0:
-11 x = 3 + 36
3 + 36 = 39:
-11 x = 39
Divide both sides of -11 x = 39 by -11:
(-11 x)/(-11) = 39/(-11)
(-11)/(-11) = 1:
x = 39/(-11)
Multiply numerator and denominator of 39/(-11) by -1:
Answer: x = (-39)/11

Answer:
-2.4
Step-by-step explanation:
Let the unknown number be x.
-3.7 = -1.3(1) + x
-3.7 = -1.3 + x
x - 1.3 = -3.7
x = -3.7 + 1.3
x = -2.4
6. Calculate the slope of the line given the two points: (4,9) and (7,11).
What is an equation of the line that passes through the point (2,-5) and is parallel
to the line 6x +y = 6?
Answer:
y = -6x + 7
Step-by-step explanation:
In this question, we need to find the equation of a line with the given information.
We know that the line passes through (2, -5).
We also know that the line is parallel to the line 6x + y = 6, which means that it has to have the same slope.
To make it simpler to understand, we can change the equation into slope format:
y = -6x + 6
This means that our new line should have a slope of -6.
With the information above, we can plug in our new values to get the y-intercept of our equations, since we don't have that information.
Plug in your slope and coordinates to the y = mx + b equation and solve for b:
-5 = -6(2) + b
-5 = -12 + b
Add 12 to both sides.
7 = b
Our y-intercept would be b.
Now, we can plug in all our information to get our new equation:
y = -6x + 7
Your answer would be y = -6x + 7
Angle DFG and Angle JKL are complementary angles. mAngle DFG= x+8.0 and mAngle JKL= x- 5.8 Find mAngle JKL
Answer:
m<JKL = 38.1
Step-by-step explanation:
We are given 2 angles, <DFG and <JKL, which are complementary angles, also that m<DFG = x+8.0 and m<JKL = x-5.8
Complementary angles are angles that add up to 90.
This means that m<DFG plus m<JKL is equal to 90.
As an equation, that would be:
m<DFG + m<JKL = 90
We can substitute m<DFG and m<JKL with their measures.
x + 8.0 + x - 5.8 = 90
Combine the x's.
2x + 8.0 - 5.8 = 90
Subtract 5.8 from 8.0.
2x + 2.2 = 90
Subtract 2.2 from both sides
2x = 87.8
Divide both sides by 2.
x = 43.9
We found the value of x, but we aren't done yet. The question wants us to find the measure of <JKL.
Remember that m<JKL=x-5.8
So, replace 43.9 as x and subtract 5.8 from it.
m<JKL = x-5.8 = 43.9 - 5.8 = 38.1

Write an equation of the line that passes through (3, 7) and is parallel to the line shown. (1, 4) (- 2, - 2)
Answer:
y=2x+1.
Step-by-step explanation:
You first need to find the slope of the line already graphed. -2 to 1 would be three units to the right, and -2 to 4 would be six units up. You would use the equation (y2-y1)/(x2-x1), where x1 and y1 would be the x and y values of the first coordinate of the graphed line, and x2 and y2 would be the second coordinate. This would be 6/3, which can be simplified to 2/1, which can be simplified to 2, which would mean the slope of the given line would be 2, as well as the parallel line. Now, you could use a pretty complicated equation to find the y-intercept of the line you need to graph, but I would recommend using the slope to find it. Since the given point is (3, 7), you would need to go to the left, meaning you would reverse the slope until you reach the y-axis, so you would use -2 as the slope. 3*-2=-6, and 7-6=1, so the y-intercept would be 1. The answer would be y=2x+1. Hope this helps.
