Exercise 56 Page 144

A reflection in the y-axis means to replace all of the x-values of the coordinates with their opposites.

Q'(4,4), R'(2,2), S'(2,-1), and T'(4,-3)

Practice makes perfect
We have been asked to reflect the given trapezoid in the y-axis. This means that we replace all x-values of the coordinates with their opposites.

Therefore, we get the points Q'(4,4), R'(2,2), S'(2,-1), and T'(4,-3).
