Question

1. what does translating a shape 3 units up do to its y - coordinates? a. it adds 3 to them. b. it divides them by 3. c. it negates them. d. it subtracts 3 from them.

Explanation:

Step1: Recall translation rules

In a coordinate - plane, when we translate a shape vertically, the x - coordinates remain the same and the y - coordinates change. Translating a shape up means increasing the y - values.

Step2: Determine the change in y - coordinates

If we translate a shape 3 units up, we add 3 to the y - coordinates of all the points of the shape.

Answer:

a. It adds 3 to them.
