Question

Give the coordinates for the image of R (0, -5) E (4, -3) C (6, -5) T (2, -7) when it is reflected across the line y = x.

Answer 1

Below.

Explanation:

The x and y coordinates flip with this reflection e, g (2, 1) goes to (1, 2).

So R (0, -5) ---> R' (-5, 0).

E (4, -3) ---> E' (-3, 4).

C (6, -5) ---> C' (-5, 6).

T (2, -7) ---> T' (-7, 2).
