Question

Which ordered pair represents the reflection of the point (5,1) over the y-axis?

Answer 1

We are asked to reflect a point over the y-axis. To solve this question, we simply need to know the transformation for reflection.

The transformation for reflection across the y-axis is:

`(x,y)\to(-x,y)`

Let us apply the transformation on the question.

`\begin{gathered} (x,y)\to(-x,y) \\ (5,1)\to(-5,1) \end{gathered}`

Answer

The answer is (-5, 1)
