Write the equation of the line PERPENDICULAR to x = -12 passing through (4,5)

hope ithelps :)

Step-by-step explanation:

1) x=3 is a vertical line, so if you are looking for a line that is perpendicular you are looking for a horizontal line.

And horizontal lines go through the y-axis and have equations of y= a #

2)the point on the vertical line is (4,-5), it has a y-value of -5

Every y value on a horizontal line will be the same

so the equation for a perpendicular line would be y= -5
