Question

4. Write an equation for a line that isperpendicular to y = -4.

Answer 1

The equation y = -4 is a horizontal line at the point -4 in the y-axis.

In order to find a perpendicular line to this equation, we can choose any vertical line in the form:

`x=a`

Where 'a' is any real constant.

So an equation for a line perpendicular to y = -4 would be:

`x=2`
