With vertices d(2, 5), e(6, 4), and f(3, 3), is reflected across the line y=x a student determined one of the vertices on the image to be (2, –5). evaluate the student’s answer

The point (2, -5) would not be one of the correct vertices of the reflected shape.

When we reflected a shape across the line y=x, we just replace the x's with y's and y's with x's.

Our new points are (5, 2) (4, 6) and (3, 3). None of the points contain negative numbers.
