Answer:
A''(1,-1) B''(2,2) C''(5,2)
Step-by-step explanation:
Points A(1,−5) B(2,−2) C(5,−2)
reflection over y=-1
Perpendicular distance between points y-coordinates of points (A, B and C) and y=-1 are 4,1 and 1
after reflections, the perpendicular distance will be 8,2,2 and the points will be at
A'(1,3) B'(2,0) C'(5,0)
again reflection over y=1
Perpendicular distance between points y-coordinates of points (A', B' and C') and y=1 are 2,1 and 1
after reflections, the perpendicular distance will be 4,2,2 and the points will be at
A''(1,-1) B''(2,2) C''(5,2)!
