Could someone explain to me how to do this???Points A and A' have symmetry with respect to the line two units above, and parallel to, the x- axis. Graph the points for A', B', C', and D'.

When A is (1, 1), A' is...?
When B is (-3, 0), B' is...?
When C is (3, 4), C' is...?
When D is (-2, -1), D' is...?

Yeah I know.. I usualy dont have issues with this sort of graphing. But the A' B' thing has me kinda confused.

563blackghost · Answer

yea me too

the only thing i know is it's horizontal x'D but other than that i'm confused.

@Vocaloid a little help.

rosalina134 · Answer

I thought it would be like the opposite like A (1,1) A' -1,-1 and then I figured that would be too easy, so that cant be right lol :')

563blackghost · Answer

Maybe you plot the point and create a line from it. You would then move the point 2 units down and get you line that parallel and respect from the line you created???

Such as A is (1,1) then we move down 2 units...(1,-1)???

That is the only thing I can think of.

rosalina134 · Answer

Thats the other thing I was thinking.. Other than that I really don't even know :(

rosalina134 · Answer

Well could you try to help me with this while I see if vocaloid can help me with the other one? I literally only have 3 questions left and these are the ones that have me stumped.. Here it is if so... http://prntscr.com/hmluhq

Go down the list of this. https://www.desmos.com/calculator/cfaokmuk8i

563blackghost · Answer

What have you put down so far. For the parabola one.

rosalina134 · Answer

Is the desmos link for the parabola question?? I read thru it.. I'm still having a really hard time understanding how to do it though...

563blackghost · Answer

no that one is for the graphing one..

rosalina134 · Answer

Oh okay... I'll read thru it again and  I don't have anything down for the parabola yet, since it has me really confused.. Nothing like this was in lessons prior to it.
