If quadrilateral A(-1,2), B(1,1), C(1,-1), D(-2,-2) rotates90 degrees counterclockwise about the origin, what are the coordinates of A' in quadrilateral "A'B'C'D'

Square EFGH stretches vertically by a factor of 2.5 to create square E’F’G’H’. The square stretches with respect to the x-axis. If point H is located at (-2,0) what are the coordinates of H?

I'm actually not entirely sure how to do either of these, but the second one would seem like it's either still (-2,0) or (-2, 2.5) depending on how these work. Do you have the correct answers or choices or anything? (I haven't taken geometry in a while, sorry)

i have the choices (-5,0), (-2,0), (0.5,0), (2.2,5) in my notes i wrote trick question... :/

i think i can find the point and slope y = 2.5 + 5 but not sure
