Question

Triangle CDE with vertices C(1, -1), D(2, 3), and E(3,-2) is reflected in line x= 4.

What are the coordinates of D’?
(7,-1)
(5,-2)
(6,7)
(6,3)

Answer 1

(6,3)

Explanation:

Two is two away from four and since it is on the left side, you add to get six as your x coordinate. The y coordinate stays the same.
