Question

Point P has coordinates (2, 3). Point Q is symmetric to point P with respect to the line x = 4.

What are the coordinates of point Q?


(2, 5)


(5, 3)


(3, 6)


(6, 3)

Answer 1

(6,3)

Explanation:

The line x = 4 is a vertical line on the coordinate grid which passes through the x-axis at the point where x = 4. So the x coordinate of Q will be the same distance after x = 4 as P is before it. That is where x = 4+2 = 6. The y coordinate will be the same as that of P.

Answer 2

D as x originally was 2 and 4 added makes it 6
