Question

Given ABC show below plot its reflection across the line y= -2 label the image A’B’C show how the three vertices get maped below.

Answer 1

The graph of the transformation of ABC is added as an attachment

How to determine the image of the transformation

From the question, we have the following parameters that can be used in our computation:

A(1, 1), B(1, 3) C(3, 1)

First, we graph the triangle ABC

This is the given figure 1 in the question

Next, we reflection across the line y= -2

This means that we mirror the figure across the line y = -2

So, we have

A'(1, -5), B(1, -7) C(3, -5)

The graph of the transformation is added as an attachment
