Answer:

(5, -2)

Step-by-step explanation:

1. The equation x=3 describes a vertical line. A perpendicular line will be horizontal. It will have no "rise" for any length of "run." The slope is zero.

2. The point-slope form of the equation for a line with slope m through point (h, k) is ...

y -k = m(x -h)

You can read the values of h and k from your equation. They are ...

h = 5
k = -2

So, a point on the line is (h, k) = (5, -2).
