Answer: The image ∆P'Q'R' on the coordinate plane is attached.

Explanation:

A rotation is defined as a transformation in which a figure is rotated about a point called "The center of rotation"

The Rule for 90° counterclockwise rotation about the origin is:


(x,y)
(-y,x)

Observe in the picture that the coordinates of the vertices of the triangle PQR are :


P(1,-1)\\\\Q(3,-2)\\\\R(3,-4)

Therefore, applying the Rulefor 90° counterclockwise rotation about the origin we get that the coordinates P'Q'R' are:


P'(1,1)\\\\Q'(2,3)\\\\R'(4,3)

Knowing these coordinates, you can draw it on the coordinate plane (Observe the picture attached)
