Answer:
B'(-3, 2)
Explanation:
In the triangle, point B is at (3, 2).
We want to find the coordinates of B', the image of B when triangle ABC is reflected over the y-axis.
When a point (x,y) is reflected over the y-axis, the transformation rule is:
![(x,y)\to(-x,y)](https://tex.z-dn.net/?f=%28x%2Cy%29%5Cto%28-x%2Cy%29)
This means that the x-coordinate changes to the opposite sign while the y-coordinate stays the same.
Applying this rule, we have:
![B(3,2)\to B^{\prime}(-3,2)](https://tex.z-dn.net/?f=B%283%2C2%29%5Cto%20B%5E%7B%5Cprime%7D%28-3%2C2%29)
Thus, the coordinates of point B' after triangle ABC is reflected across the y-axis will be B'(-3, 2).
