#### Answer:

0

#### Explanation:

Compare to:

The slope for

So the slope

Slope (gradient) is the amount of up for the amount of along

The slope for

The perpendicular to the y-axis is parallel to the x-axis. In this case

So the slope (gradient) perpendicular to

There is no up for any amount of along!
