Question

What is the slope of the line passing through the points (- 1, 7) and (4, - 1)?

a.) - 2 b.) 2 c.) - 5 / 6 d.) - 8 / 5

Answer 1

d. -8/5

Explanation:

Given points

Let (x1 ,y1) = ( 4 , -1) and (x2 , y2) = ( -1 , 7)

Now

slope (m)

`= (y2 - y1)/(x2 - x1) \\ = (7 + 1)/( - 1 - 4) \\ = ( - 8)/(5)`
