(4,6)

Because we are flipping with respect to the y-axis, the y-coordinate will not change. Since the y-axis is the mirror the point will be the same distance from it, just on the other side, so the x-coordiante changes signs.

Yes that makes sense now!! Thank you!

Oh wow I'm sorry I was think of the x axis!

Do you  think you could help me out with two more? For some reason these completely confuse me

anonymous · Answer

Sorry for the crappy drawing; I think it still makes sense.

anonymous · Answer

Ya I can help.

(8, -1) is reflected over the line y = x. What are the coordinates of the image?

(9, 3) is reflected over the x-axis. What are the coordinates of the image?

Thanks!!!!

|dw:1399066249033:dw|  A flip about y=x is the inverse, so we swap the x and y coordinates.
