Answer: The slope perpendicular to the line is = 0

Step-by-step explanation:

the line x= -3 is a special case of the equation of a straight line.

It is a vertical line, and since it parallel to the y-axis, it’s slope is undefined

A line perpendicular to it must be a horizontal line parallel to the x-axis

Parallel to the x-axis means the slope = 0

Answer: 0

Step-by-step explanation:

Slope of x = -3 is infinite / undefined (there is infinite/no defined change in y for a given change in x). Remember, line x = -3 slopes straight up.

Perpendicular means at a 'right angle to'.

The only kind of line that is perpendicular to a vertical line is a horizontal line, which is like y = 15 or y = 5 or something. The slope of such lines is always zero, because there is no change in line's rise for a given run.
