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.

2 answers

the choices are
A. P'(4,7),Q'(8,7),R'(3,-3)
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)
but I think its "c" can anyone help me??
good grief!

bobpursely already pointed out that you had a typo.

how hard is it to switch around the x and y variables in your points

e.g Q(-7,-8) ----> Q'(-8,-7)

look at you P, none of the choices given are correct, so where do you think the typo is ?
