14. Which graph has an undefined slope?

Given:

Slope is undefined.

To find:

Which graph has an undefined slope?

Solution:

We know that, slope is change in y-values with respect to x-values.

The slope is undefined if the denominator is 0.

It means, the x-values are same. It is possible only for a vertical line.

Therefore, the slope of vertical lines are undefined or we can say that graph of a vertical line has an undefined slope. It is of the form , where, a is a constant and it can be any real number.

answer: check all that apply, where the options?
