Answer:

 The answer is L'(-2,2), M' (-6,4), and N' (-5,-4)

Step-by-step explanation:

Mapping Rule for 90 Counterclockwise Rotations

1) switch the x and y coords

2) multiply the new x coords by -1

3) Simplify

(x,y) --> (-y,x)

Example Problem

Rotate the point N(2,-4) 90 counterclockwise around the origin.

N(2,-4) --> N' (4,2)

I hope this helps you. I know the example problems always helped me understand.
