What is the equation of the line that passes
through the point (-2,2) and the point (-6,4)?
Answers
Answer:
y = -1/2x+1
Step-by-step explanation:
First step is to find the slope
m = (y2-y1)/(x2-x1)
= ( 4-2)/(-6 - -2)
(4-2)/(-6+2)
2/-4
-1/2
Then we can use the slope intercept form of a line
y = mx+b where m is the slope and b is the y intercept
y = -1/2x+b
Substitute a point into the equation to find b
2 = -1/2(-2) +b
2 = 1+b
Subtract 1 from each side
1 =b
y = -1/2x+1
y = mx + b
Where m = slope and b is the y intercept
Let's find the slope = change in y/change in x
m = (4-2)/(-6+2) = 2/-4 = -1/2
Now we have:
y = (-1/2)x + b
Now substitute point (-6,4)
4 = (-1/2)(-6) + b
4 = 3 + b
b = 1
So y = (-1/2)x + 1 is the equation

[tex]y=(-\frac{1}{2})x[/tex]+1

1. Mrs. Rodger got a weekly raise of $145. If she gets paid every other week, write an integer describing how the raise will affect her paycheck.
Answers
weekly raise= $145
to find:an integer describing how the raise will affect her paycheck.
solution:Let the 1st paycheck be x (integer).
Mrs. Rodger got a weekly raise of $ 145.
So after completing the 1st week she will get $ (x+145).
Similarly after completing the 2nd week she will get $ (x + 145) + $ 145.
= $ (x + 145 + 145)
= $ (x + 290)
therefore, in this way end of every week her salary will increase by $ 145.

Gagu is paid £1200 per month.
He is going to get a 4% increase in the amount of money he is paid.
Work out how much Gagu will be paid per month after the increase.
Answers
Answer:
£1248
Step-by-step explanation:
1200x4%
=£48
1200+48=£1248
Gagu will be paid £1248 after the increase.
The amount Gagu paid per month after the 4% increment is £1248
What is the method to calculate x% increment?If there is x% increment in y then the increment will be (x/100)*y and the new amount after x% increment will be now y + (x*y)/100
Given that Gagu is paid £1200 per month. He is going to get a 4% increase in the amount of money he is paid.
Initial payment = £1200
4% increment = 4% of initial pay = 4(1200)/ 100 = £ 48
After increment new payment = Initial payment + 4% increment = 1200+48
= £1248
Therefore, The amount Gagu paid per month after the increase is £1248

driveway. One circle has an area of
200.96 inches. What is the radius of
one of the circles?
Answers
Answer: The radius is 8 inches
Step-by-step explanation:
The formula for the area of a circle is [tex]\pi r^2=A[/tex]
Where
A is the area (200.96 for this)
[tex]\pi[/tex] is pi (we'll round it to 3.14 for this)
and r is the radius
Let's sub in our values and solve for r
[tex]3.14r^2=200.96[/tex]
Divide both sides by 3.14 to isolate [tex]r^2[/tex]
[tex]\frac{3.14r^2}{3.14} =\frac{200.96}{3.14} \\\\r^2=64[/tex]
Take the square root of both sides to cancel the square
[tex]r^2=64\\\sqrt{r^2} =\sqrt{64} \\r=8[/tex]

These are also people who believe they can make it big as artists, but they wish to be white to do so. Black artists think they can't be accepted as people, let alone artists. So the mountain in the essay represents a huge obstacle these people have to achieve.
