If it was 23 degrees below zero it would be -23 degrees
Answer:
slope = 0
Step-by-step explanation:
The line with equation x = - 3 is a vertical line parallel to the y- axis
A perpendicular line is therefore a horizontal line parallel to the x- axis
The slope of the x- axis is zero, hence the slope of the horizontal line is
slope = 0
