Alex_Xolod [135]

Answer:

slope  that is undefined

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = A(- 3, 5) and (x₂, y₂ ) = B(- 3, 3)

m = \frac{3-5}{-3+3} = \frac{-2}{0}

Division by zero is undefined

Thus the slope of AB is undefined
