Question

Triangle CAT has vertices C(-4,5), A(3,-1), and T(-2,-7). What are the coordinates of the image after a reflection over the y-axis? Remember to includes parentheses and do NOT include any spaces.

C'
А'
T'​

Answer 1

C(-4,-5), A(3,1), T(-2,7). X values of the coordinates remain the same while Y values change their signs. This is because the point will not move vertically when reflecting over the Y-axis, but it will have the same horizontal distance from the y-axis in the opposite direction.
