with vertices D(2, 5), E(6, 4), and F(3, 3), is reflected across the line A student determined one of the vertices on the image to be (2, –5). Evaluate the student’s answer
The vertices of the image reflected over the line y = x are: D´( 5 , 2 ), E´( 4, 6 ) and F´( 3, 3 ). So ( 2, -5 ) is incorrect and it could be incorrectly reflected across over the x-axis.
