Question

- Graph the reflection of rectangle PREZ over the y-axis.P(-2,1), R(-2,-4), E(-5,-4), and Z(-5,1).

Answer 1

when we apply a reflection over the y-axis we change the sign of the x component of each point

$\begin{gathered} P(-2,1)\longrightarrow P^{\prime}(2,1) \\ R(-2,-4)\longrightarrow R^{\prime}(2,-4) \\ E(-5,-4)\longrightarrow E^{\prime}(5,-4) \\ Z(-5,1)\longrightarrow Z^{\prime}(5,1) \end{gathered}$

now graph each new point
