Question

Line CD contains points A (4, 6) and B (4, 3). The slope of line CD is (2 points)

Answer 1

Answer:

slope is undefined

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = A(4, 6) and (x₂, y₂ ) = B(4, 3)

m = $\frac{3-6}{4-4}$ = $\frac{-3}{0}$

Division by zero is undefined thus the slope of CD is undefined
