Answer 1

ANSWER

B'(5,-2).

EXPLANATION

The coordinates of B are (-2,5).

We want to find the image of this point after a reflection in the line y=x.

The mapping is

$(x,y)\to (y,x)$

We just have to swap the ordered pairs.

$( - 2,5)\to (5, - 2)$

Hence the image of B(-2,5) is B'(5,-2).

The correct answer is (5,-2).
