##### 1 Answer

See the solution process below:

#### Explanation:

This equation is in standard linear form. The standard form of a linear equation is:

Where, if at all possible,

The slope of an equation in standard form is:

A line parallel to this line will have the same slope as:

Let us call the slope of the perpendicular line

The formula for the slope of a perpendicular line is:

Substituting gives the slope of the perpendicular line as:
