II
I
IV

Answer 1

@tomster135

Answer 2

Do you have any guesses?

Answer 3

IV

Answer 4

Okay, so a reflection is basically a "flip". We want a "flip about the horizontal axis.

Answer 5

Guess again.

Answer 6

What is your thought on this @sparkle✴ What do you think the answer is. It is most certainly like the previous problem, but just across the x-axis instead of y. Give it some thought and let me know.

Answer 7

Condawg's explantion of a "reflection" is a good thing to go off of.

Answer 8

i thought it was IV because the opposite of 5 is -5

Answer 9

IV doesn't go to -5, it goes to -4.

Answer 10

oh lol

Answer 11

so II

Answer 12

:P look for on that is a PERFECT flip about the X axis. II is a perfect flip about the y axis, the vertical line. We want the perfect flip about the x axis, the horizontal one. So instead of flipping left and right, it will flip up and down.

Answer 13

one**

Answer 14

The best way I can give an example of this is, what if you folded a piece of paper, where would the figure lay. That is the best way that has always helped me, always. The X-Axis is horzontal (the line that goes across from right to left), then the Y-Axis is vertical (the line that goes up and down). Exactly as Condawg just mentioned.

Answer 15

so its I

Answer 16

Right!

Answer 17

no its III

Answer 18

Look close. Look at the numbers of III, if it's a perfect flip the numbers should be opposite. Like 5 to -5.

Answer 19

Recap

Answer 20

A reflection about the x axis is a perfect flip going up and down. A reflection about the y axis is a perfect flip going left and right.
