Answer:
The equation of this line would be y = 0.
Step-by-step explanation:
In order to find this, we must first note that this is a vertical line (x = 5). Since it is vertical, we know the perpendicular line is horizontal. All horizontal lines are written in the form of y = (a number). Given that we have a y value in the ordered pair, we simply plug that in for what y is equal to.
y = 0
