Answer 1

@math1234 could u please help me?

Answer 2

@robtobey sorry to bother you again but would u by a chance know how to help me do this one? I think it is (3,7)

Answer 3

Ok, first of all, you are trying to reflect the image across x=3.

Answer 4

x=3 is a vertical line. Do you agree?

Answer 5

Yes. so x would go to 3 on the graph right?

Answer 6

I was confused if i move it 3 units up or 3 to the right

Answer 7

Think more carefully, the image is being reflected across the line. So imagine placing a mirror along the x=3 vertical line.

Answer 8

So x would be on 7?

Answer 9

Correct.

Answer 10

And think about your y now.

Answer 11

If the image is being reflected across a vertical line, would any of your y coordinates change?

Answer 12

5?

Answer 13

Yes, correct.

Answer 14

So your reflected image of X is (7, 5)

Answer 15

OK i was thinking 3 or 5 y would be on. it was hard to kind of mirror it.

Answer 16

thank you for helping me!!
