Question

Which sequence of transformations produces a congruent figure? (−x, y)(x−4, y+2) (x+2, 2y)(x+1, y−4) (x+2, y)(−x, −2.5y) (−x, 3y)(x−2, y)

Answer 1

(−x, y)(x−4, y+2)

Explanation:

If the figure is to be congruent, there must be no dilation. Any transformation having a multiplier on x or y cannot be a solution.

The only remaining choice is the one shown above, which involves a reflection across the y-axis and a translation.
