Question

Find the slope of the line passing through the points (9,2) and (9,-5)

Answer 1

Answer:

slope is undefined

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (9, 2) and (x₂, y₂ ) = (9, - 5)

m = $\frac{-5-2}{9-9}$ = $\frac{-7}{0}$

Since division by zero is undefined then the slope is undefined.

This indicates that the line is vertical.
