Step-by-step explanation:
3. B
because the figure to the left of the y-axis yields the one to the right when you reflect it across y = x.
4. C
Flip either of the figures vertically across x = -1 which is their intersection point and you'll get the other.
5. D
it can't be clockwise because the x value of the vertices would have been negative. so it is 270° counterclockwise resulting in ( -y , x )
6. A
Similar to #4 which except this time, you flip it horizontally like how you lay a book or pick it up.
