Question

Given points j(2,5), a(6,6), and R(,4,2), graph Jar and its reflection image across the given line

Answer 1

First, we need to locate the points J, A and R:

J is in red, A is in green and R is in purple.

Now to make a reflection across the y-axis, we need to multiply the x-coordinate of each point by (-1):

`\begin{gathered} J(2,5)\Rightarrow J^(\prime)(-2,5) \\ A(6,6)\Rightarrow A^(\prime)(-6,6) \\ R(4,2)\Rightarrow R^(\prime)(-4,6) \end{gathered}`

And we get:

Which is the reflection across the y-axis
