Which graph shows the image of the triangle reflected across the line of reflection shown I can’t post the choices but if you’ve taken the test on edg please help

Here we have to find the distance of the points from the mirror, and then plot it on the other side of the mirror.

Step-by-step explanation:

⇒Here the x-coordinate will not change

the point(4,2)is one unit far from the mirror. then we will plot it on the other side of the mirror which is (4,4)

we will do same with the other two points.

here are the changes:

(4,2)⇒(4,4)

(2,4)⇒(2,2)

(9,6)⇒(9,0)

then join the new points.

Hope it helps!
