Question

What is the slope of the line that contains the points (9,-4) and (1,-5)?

A. 1
B. -1/8
C. -1
D. 1/8

Answer 1

B

Explanation:

Answer 2

Answer:
`\bold{D.\ (1)/(8)}`

Explanation:

Plug the given coordinates (x₁, y₁) = (9, -4) and (x₂, y₂) = (1, -5) into the slope formula to find the slope (m):

`m=(y_2-y_1)/(x_2-x_1)\\\\m=(-5-(-4))/(1-9)\\\\.\quad =(-5+4)/(-8)\\\\.\quad =(-1)/(-8)\\\\.\quad =(1)/(8)`
