Question

Triangle DEF, 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.

A.
The student performed the reflection correctly.
B.
The student incorrectly reflected across over the x-axis.
C.
The student incorrectly reflected across the y-axis.
D.
The student incorrectly reflected across the line y = –x.

Answer 1

B. The student incorrectly reflect the cross over the X axis

Explanation:

Answer 2

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.
Answer: B)
