Answer:

x = -3

Explanation:

The line y = 3 is a horizontal line. So a perpendicular line is a vertical line. The form of the equation for a vertical line is

"x = anumber"

The information we have to work with is the point (-3, 10) A point is in the form (x,y). So we know that x is -3 and y is 10.

We need the x.

x = -3

This is the equation of the vertical line through (-3,10). It is perpendicular to the horizontal line

y = 3.

Answer:

x = -3
