Reflect the point (1,5) across the line y=2x+1 to obtain the point p. Determine the coordinates for p.
The coordinates of the reflected point are (−75,−115)
Step 1 :Plug the values into the formula:
Step 2 :x′=1−2(5−1)1+22=−75
Step 3 :y′=2(1−1)+5(1−22)+2(1)1+22=−115
Step 4 :The coordinates of the reflected point are (−75,−115)
