Answer:
slope is undefined
Step-by-step explanation:
calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 9 ) and (x₂, y₂ ) = (- 2, 5 )
m = [tex]\frac{5-9}{-2-(-2)}[/tex] = [tex]\frac{-4}{-2+2}[/tex] = [tex]\frac{-4}{0}[/tex]
since division by zero is undefined then the slope of the line is undefined
