Question

What is the slope of the line that passes through the points (-9, -9) and (-9, -7) Write in simplest form.

Answer 1

Answer:

Undefined slope, vertical line

Step-by-step explanation:

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

Slope = $\frac{-7 -(-9)}{-9-(-9)} = \frac{-7+9}{-9+9} =\frac{2}{0}$ = Undefined

Since the slope is undefined, you would have a vertical line.
