Question

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

Answer 1

Answer:

B

Step-by-step explanation:

Answer 2

Answer:   $\bold{D.\ \dfrac{1}{8}}$

Step-by-step explanation:

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

$m=\dfrac{y_2-y_1}{x_2-x_1}\\\\m=\dfrac{-5-(-4)}{1-9}\\\\.\quad =\dfrac{-5+4}{-8}\\\\.\quad =\dfrac{-1}{-8}\\\\.\quad =\dfrac{1}{8}$
