Question

What is the image of O(-3,-2) after two reflections, first across the line y=-5, then across the line x=1?
A. (-3,-8)
B. (-3,-2)
C. (5,-2)
D. (5,-8)

Answer 1

across y=-5: (x,y)->(x,-5-(y- -5)) = (x,-10-y)
across x=1: (x,y)->(1-(x-1),y) = (2-x)

now just use them both; they are independent. Check using some graph paper.
