Answer:
y = 2/5x - 1/5
Step-by-step explanation:
The first step is to find the slope. We can do this by doing y2- y1/x2 - x1, you can name any number 1 or 2 as long as the x and y are right.
-1 - (-3)/-2 - (-7) = 2/5
Now that we know that the slope is 2/5 we can use the formula
y - y1 = m(x - x1)
y + 3 = 2/5(x +7)
y + 3 = 2/5x + 2 4/5
y = 2/5x - 1/5
