The equation formula is y - y1 = m(x-x1)
Using the first point for x1, y1:
Y +13 = m(x-15)
M is the slope which is the change in y over the change in x:
M = -11–13 / 16-15 = 2/1 = 2
The equation becomes y +13 =2(x+15)
The answer is:
He incorrectly wrote the slope in his equation. He should have written y+13=2(x−15).
