A rectangle with vertices M(-7, -2), N(-5, -1), O (-2, -7) and P(-4, -8) is rotated 90 degrees counter clockwise about the origin. What are the new locations of the vertices?

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

in the simple case, the two triangles point x and y are congruent because every corresponding side has the same length, and every corresponding angle has the same measure.
