Please help! I don't understand this. I need to transform using Do,3(r(x=y)). Or in other words; reflect over like x=y then dialiate by 3. How do I reflect over x=y. No typo. Thanks! The coordinates are A. (-2,1), B. (2,1), C. (2,-2), D. (-2,2)
When you reflect point across a 45 degree sloped line (r(x=y)), the coordinates are flipped. So A (-2,1) reflected is (1,-2) B(2,1) reflected is (1,2) C(2,-2) reflected is (-2,2) D(-2,2) reflected is (2,-2)
