Question

perform a glide reflection by translating ABC right 2, 4, then reflect across the y-axis. five the coordinates for the first image A' B' C'pre-image A(3,11) B(3,4) C(10,4)

Answer 1

The glide reflection that concerts the pre-image of the points:

A = (3, 11)

B = (3, 4)

C = (10, 4)

to the right 2 units is given by adding to the x coordinate 2 units. These points then become:

A' = (3 + 2, 11) = (5, 11)

B' = (3 + 2 , 4) = (5, 4)

C' = (10 + 2, 4) = (12, 4)
