Question

I WILL GIVE BRAINLIEST TO WHOEVER IS CORRECT.

Answer 1

The correct answer is A m8 :P

Answer 2

What would you think??

The line t is a vertical line. When you reflect something across a vertical line, it retains the same vertical point but not the same horizontal point.

Like, reflecting (-5, 5) across the y-axis(in this case, the y-axis is named t) is:
(5, 5).

So now do the same.

Q is 5 units left away from line t. So go 5 units right away from line t.
R is 7 units left away from line t. So go 5 units right away from line t.
S is 2 units left away from line t. So go 5 units right away from line t. 

And you get your answer: Answer Choice A.
