Write an equation of the line passing through point$P(4,-6) that is perpendicular to the line y=-3 . x=

x = 4

Step-by-step explanation:

y = - 3 is the equation of a horizontal line parallel to the x- axis.

A line perpendicular to it will therefore be a vertical line parallel to the y- axis with equation

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (4, - 6) with x- coordinate 4, thus

x = 4 ← equation of perpendicular line

answer: the correct one is a
