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 = [tex]\frac{-5-2}{9-9}[/tex] = [tex]\frac{-7}{0}[/tex]
Since division by zero is undefined then the slope is undefined.
This indicates that the line is vertical.
