Answer 1

"Graph the image for the rotation"

Answer 2

Don't do that, just apply the rule :
90 degree counterclockwise send (x,y) to (-y,x)
so, you just label the coordinate of the points, like this
R(-1,-1), so x =-1, y =-1, now, it will turn to R'(-y,x)
from R, y =-1, hence -y =1, x just stay, hence R'(1,-1), now, you point it out
do the same with Q, Z, E
link them all
I do R and Q for you
R (-1,-1)--> R'(1,-1)
Q(3,-2) ---> Q'(2,3)

Answer 3

I'm using https://app.geogebra.org/#geometry

Answer 4

You look at Q, Q', if Q' is on the y axis, then Q must be on the x axis so that they make a 90 degree , right? but your graph is not.
