A triangle has points A(2,3) B(2,6) and C(7,3) 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 b coordinate

Answer 1

After reflecting the triangle over the x-axis, the coordinates of A, B, and C become A'(2,-3), B'(2,-6), and C'(7,-3) respectively.

Then, after reflecting the triangle over the line y=x, the coordinates of A', B', and C' become A''(-3,2), B''(-6,2), and C''(-3,7) respectively.

Therefore, the b coordinate of the point B'' is 2.
