Question

Find the equation of a line that contains the points (-8,0) and (-8, –6).

Answer 1

Answer:   x = -8

Explanation:

Both points have the same identical x coordinate, so this line is completely vertical. Vertical lines are always of the form x = k, where k is some constant.

The equation must be x = -8 since we want both x coordinates to be -8.

Side note: The slope of this line is undefined, which applies to any vertical line.
