Which choice shows the coordinates of c’ if the trapezoid is reflected across the y-axis?

(–5, 3)
(3, –5)
(5, –3)
(–3, 5)

A reflection through the axis and is given by the following transformation rule:
 (x, y) > (-x, y)
 We have the following point:
 C = (5, 3)
 Applying the transformation rule we have:
 (5, 3) > (-5, 3)
 Therefore, C' is given by:
 C '= (- 5, 3)
 
 (-5, 3)
