Question

please help me with this question:

A figure is translated as such: (x, y) ------> (x + 2, y - 4). What would will move the figure back to its original position?

Answer 1

x+2-2=x

y-4+4=y

(x,y) means back to the original position.

so -2 you need to move right 2 units at x axis direction

+4 you need to move up 4 units at y axis direction

Answer 2

What is the reverse of adding 2?

What is the reverse of subtracting 4?
