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 ) = (- 3, 4 ) and (x₂, y₂ ) = (- 3, - 7 )

m = [tex]\frac{-7-4}{-3+3}[/tex] = [tex]\frac{-11}{0}[/tex]

Since division by zero is undefined then the slope is undefined

This indicates the line is vertical and parallel to the y- axis
