Question

I need some help, I have one-half of the problem done. But I don't exactly know how to do the other.

Answer 1

The coordinates of point A on a grid are (5, −3). Point A is reflected across the x-axis to obtain point B. The coordinates of point B are (5, ___).

Answer 2

This is the grid I had to draw for 5, -3 if it is right or helps.

Answer 3

When you reflect across the x-axis, the y-value is going to switch signs

So if the y-value was positive, it would become negative
If it was negative, it would become positive

The x-value stays the same

Answer 4

So, would it be -5, 3?

Answer 5

why did you change the sign for the x-value?

the x-value should remain the same

Answer 6

Oh.

Answer 7

you're only reflecting across the x-axis

so only the y-coordinate changes from positive to negative or the other way

Answer 8

But I don't know how to reflect it.

Answer 9

you just draw the point in the new location

Answer 10

So, do I just put the 5 on the opposite side? lol sorry I don't get how to do graphs*

Answer 11

What do you mean opposite side?

The 5 is the x-coordinate and it remains the same

Answer 12

So then do I change the 3?

Answer 13

You changed it from -3 to 3

Answer 14

So 5, 3?

Answer 15

That's what you get when you reflect it

so you originally have (5, -3) on your graph

and when you reflect it, you get the new point A' (5, 3)

Answer 16

Yup!

Answer 17

Ohhh, THANKS I UNDERSTAN NOW!! I appreciate it!

Answer 18

You're welcome!!
