RSTis graphed on a coordinate plane below. The triangle undergoes two transformations and the new vertices are R"(4,2), S"(8,2), and T"(8,-6). Determine
the transformations and the order in which they were applied.

A. 90° counter-clockwise rotation, then reflected across the y-axis

B. Reflected across the y-axis, then a 90° counter-clockwise rotation

C. 90° counter-clockwise rotation, then reflected across the x-axis

D. Reflected across the y=x, then a 90° counter-clockwise rotation
