Question

Quizplus · Accepted Answer

The slope formula is (y2-y1)/(x2-x1). If x2 = x1, then the denominator is 0, and the slope is undefined. In this case, both points have the same x-coordinate (-5), so the slope is undefined. Both points have the same x-coordinate (-5), which means the line is vertical. A vertical line has an undefined slope.
