Answer:
The lines are perpendicular.
Explanation:
Let us draw the two lines given to see what they look like.
Line A is a vertical line at x = 4.
Line B is a horizontal line at y = 2.
If we draw these two lines together on one graph, we get the following.
As can be seen, the red line (line A) and the blue line (line B) are perpendicular to each other.
