i-Ready Lesson 2 Practice Quiz

The coordinates of figure ABCD and its image A'B'C'D' are given below.

A(2, 4) B (5,4) C(7,5) D(2,5)

A'(4, 4) B (7,4) C(9,5) D(4,5)

Which single transformation can map figure ABCD onto figure A'B'C'D'?

• Translation of 2 units down

• Translation of 2 units up

• Translation of 2 units to the left

• Translation of 2 units to the right

Micah plots triangle ABC in the coordinate plane. Its vertices are at (-2, -3), (-5, -5), and (-8, -2). He then reflects the triangle across the x-axis to form is image, triangle A'B'C'. Which coordinates represent a vertex for the image? Choose all the correct answers.

• (2, -3)

• (-2, 3)

• (5, -5)

• (-5, 5)

• (-8, 2)
