Question

A translation moves point X to X' using the rule (x,y) → (x-2, y + 1). If X' is (3,-4), what was the

original point X?​

Answer 1

X' is (5,-5)

Explanation:

Knowing that this is just a translation, we can reverse the (polarity?) of each equation, such as changing -5 to +5 to find the original answer.

With that in mind, we can add 2 to X, and -1 from Y, which puts us at, 5 on the X axis, and -5 on the Y axis.
