I need to find the slope, if it exists, for x=6

Question

I need to see if there is a slope for this problem: x=6

Answer 1

Hi Nathan;

Slope is defined as change-of-y divided by change-of-x.

(y-y₁)/(x-x₁)

This is a vertical line.  There is no change of x.  Because a denominator cannot be zero, the

slope is undefined.
