Question

the vertices of a triangle are p(-7, -4), q(-7, -8) and r(3, -3) name the vertices of the image reflected across the line y = x

A: P'(4, 7), Q'(8, 7), R'(3, -3)**My Answer**
B: P'(4, -7), Q'(8, -7), R'(3, 3)
C: P'(-4, -7), Q'(-8, -7), R'(-3, 3)
D: P'(-4, 7), Q'(-8, 7), R'(-3, -3)

Answer 1

find R' (the reflection of r)

draw the reflecting line and do the reflection
