See a solution explanation below:

The equation $y = 2$ defines a horizontal line where for each and every value of $x$ ; $y$ has the same value; $2$ .

By definition, the slope of a horizontal line is $0$ .

Any line perpendicular to a horizontal line is a vertical line.

By definition the slope of a vertical line is undefined.

How do you find the slope perpendicular to y = 2y = 2?
