A triangle has points A(1,2) B(1,6) and C(3,6) and is reflected over the x-axis and then over the line y=x ABC are the coordinates of the reflected image what is the A coordinate

Answer 1

After reflecting the triangle over the x-axis, the new coordinates of A, B, and C would be A'(1,-2), B'(1,-6), and C'(3,-6).

Next, reflecting the triangle over the line y=x will transform the coordinates as follows:

A'' = (-2,1)
B'' = (-6,1)
C'' = (-6,3)

Therefore, the A coordinate of the reflected image is -2.
