For question 2, rotating about the origin counterclockwise 90 degrees would give you the point (-4,3)
Rotating the point around (-2,4) would put you at the point (0,5)
For question 3, rotating 90 degrees would give you the line (-2,2) to (-2,10)
Rotating 180 degrees would give you the line (-2,-2) to (-10,-2)
Rotating 270 degrees would give you the line (2,-2) to (2,-10)
