##### 2 Answers

#### Explanation:

First, remember that the equation

First, write

Since the slope is 5, the slope for the perpendicular line is

Since this line perpendicular to

That is our answer! To prove this, simply graph these two points.

#### Explanation:

Perpendicular lines have slopes that are **negative reciprocals** of each other.

So the perpendicular line will have a slope of

Now we can write the equation in point-slope form:
