A triangle has points A(1, 2), B(1, 6), and C(3, 6) and is reflected over the xaxis and then over the line y = x. A"B"C" are the coordinates of the reflected image. What is the A" coordinate?

reflect over y=0: (x,y) > (x,y)
A(1,2) > A'(1,2)
B(1,6) > B'(1,6)
C(3,6) > C'(3,6)
reflect in y=x: (x,y) > (y,x)
A'(1,2) > A*(2,1)
B'(1,6) > B*(6,1)
C'(3,6) > C*(6,3)
combined image: (x,y) > (y,x)
