Question

if a rectangle is translated 3 units up and 4 units right, what happens to the coordinates of its vertices? a. they are increased by 3 in the y - direction and 4 in the x - direction. b. they remain unchanged. c. they are divided by 3 and 4. d. they are scaled by 3 and 4.

Explanation:

Step1: Recall translation concept

Translation in a coordinate - plane moves a shape without changing its size, shape or orientation. When a rectangle is translated 3 units up and 4 units right, each vertex of the rectangle has its x - coordinate increased by 4 (right - movement) and its y - coordinate increased by 3 (up - movement).

Answer:

A. They are increased by 3 in the y - direction and 4 in the x - direction.
