Question

Find the slope of the line that contains the following pair of points (1,6) and (9,-4)

Answer 1

-1.25

Explanation:

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

☆ (x₁, y₁) is the 1st coordinate and (x₂, y₂) is the 2nd coordinate

Slope of line

`= (6 - ( - 4))/(1 - 9) \\ = (6 + 4)/( - 8) \\ = - (10)/(8) \\ = - (5)/(4) \\ = - 1.25`
