Chapter 11.4, Problem 26STP

To determine

To determine the coordinates of the point after it has been reflected over the $y$ axis.

Answer to Problem 26STP

  $\left(3,5\right)$

Explanation of Solution

Given:

  $\left(-3,5\right)$

Generally, $y$ axis works as a mirror.

To find the coordinate after it has been reflected over $y$ axis, consider a point $\text{A}\left(-h,k\right)$ ,

  

Then the mirror image of that point will be $\text{A'}\left(h,k\right).$

Here, $-h=-3$ and $k=5.$

Then mirror image will be,

  $\Rightarrow \text{A'(}h,k\text{)}$

Here, $h=3$ and $k=5$

So, the mirror image or coordinates of the point after it has been reflected over the $y$ axis is $\left(3,5\right)$ .

Conclusion:

Therefore, the coordinates of the point after it has been reflected over the $y$ axis is $\left(3,5\right)$ .
