A. (x,y)→(y,-x); A' is at (1, 5)
B. (x,y)→(-y,x); A' is at (-1, -5)
C. (x,y)→(-x,y); A' is at (5, 1)
D. (x,y)→(x,-y); A' is at (-5, -1)

Answer 1

D

Answer 2

Remember that people can't open the links and see it.

Answer 3

lol ok hang on

Answer 4

You need to screenshot it, the links say forbidden when we click on them. I don't know how @KGabriel99 got that answer without seeing it.

Answer 5

you sure @KGabriel99 can you see it?

Answer 6

I can guarantee it. This is VS and I have the notes for it. All x axis reflections are (x,y)->(x,-y)

Answer 7

@iloveyou;* are you taking these questions off an online class test?

Answer 8

Is that segment one?

Answer 9

I have the notes too.

Answer 10

no its hw

Answer 11

• Another way to say "reflect across the x-axis" is to say "reflect across the line y=0" since the line created by graphing y=0 is the same as the x-axis.
• An image that is a reflection across the x-axis, or across the line y=0, will have the same x-coordinates as the pre-image but opposite y-coordinates.
• Therefore, the rule for reflecting an image across the x-axis can be described as (x, y) → (x, −y).

Answer 12

Yeah he's right .-. I read the question wrong.

Answer 13

Yup.

Answer 14

I appologize @KGabriel99
