Question

Which coordinates describes the x-coordinates in the translation below ?

Answer 1

x + 0

the coordinates of the original triangle are

A(1 , - 1), B(1, - 5), C(4, - 5)

the coordinates of the image are

A'(1, 6), B'(1, 1), C'(4, 1)

note that the x- coordinates remain the same value under the translation

rule describing x- coordinates is therefore x + 0
