Answer:
A) y = 4
Step-by-step explanation:
Line AB is a vertical line, so a line perpendicular to it would have to be a horizontal line (perpendicular lines make an "x" shape with one another). Horizontal lines are written as y = ___ .
The perpendicular line also has to pass through the point (2,4). Points are written as (x, y). Therefore, the y-value in (2,4) is 4.
The perpendicular line has to be y=4 since it passes through both the Line AB and the given point.
