Isn't it a 125 degree rotation since the x axis is pointing downwards? It has to rotate a total of 125 degrees.
According to the answer key, the answer is C. u = -1.74x + 10.44.
I subbed p = x - 6 and q = y - 3 into the u = equation, but im not getting -1.74x at all.
I got u = (x - 6) cos (35) + (y - 3)sin(35).
