Question

If a point P(1, -2) is reflected across the line x = 3, what are the coordinates of its reflection image?

x=3 is a vertical line, and the point is two units to the left of that line, so when you reflect it it'll be 2 units to the right of that line. But the y value won't change. So, (5,-2)

Answer 2

hmmm....

P(1,-2) is reflected thru x=3 gives:

Ans: P'(5,-2)

Viola!
