Question

What is the slope of (-7, 0), (-7, -6)?

Answer 1

Answer:

A line passes (-7, 0), (-7, -6).

These two passed points have same x-component (x = -7).

=> This is the line which has equation: x = -7.

This is a vertical line (parallel with y axis) and the slope is undefined.

Hope this helps!
