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).
