Question

What is the slope of the line that passes through the points (1,−6) and (−8,9)? Write your answer in simplest form.

Answer 1

`- (5)/(3)`

Explanation:

`\boxed{slope = (y1 - y2)/(x1 - x2) }`

*(x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate.

Using the formula above,

slope of line

`= (9 - ( - 6))/( - 8 - 1) \\ = (9 + 6)/( - 9) \\ = (15)/( - 9) \\ = - (5)/(3)`
