Graph problems, please help!

OpenStudy (angelwings996):

Graph the relation and its inverse. Use open circles to graph the points of the inverse. (-7,-6) (-6,7) (-5, -2) (8,6)

OpenStudy (saifoo.khan):

Where are you stuck?

OpenStudy (angelwings996):

I am stuck on figuring out the inverse

hero (hero):

Draw the line y = x

OpenStudy (angelwings996):

Okay, then what

OpenStudy (saifoo.khan):

Reflect the points.

hero (hero):

and make sure that the reflected points are equidistant from y = x

OpenStudy (angelwings996):

So, I just do the opposite of the points that are given to me?

OpenStudy (saifoo.khan):

Like this: http://www.regentsprep.org/Regents/math/algtrig/ATP8b/inversegraph.gif

hero (hero):

The opposite with respect to y = x

OpenStudy (angelwings996):

Ohh Okay! I get it, could you help me with one more please?

hero (hero):

Which one did you pick?

OpenStudy (angelwings996):

I got the third one, is that right ?

hero (hero):

You're guessing :(

hero (hero):

Did you draw the line y = x ?

OpenStudy (angelwings996):

No, it looked the the reflecting of the regular one

OpenStudy (angelwings996):

Yes i did

hero (hero):

What does the first graph look like?

OpenStudy (angelwings996):

Like what do you mean? Like how did I put the y = x line

hero (hero):

Hang on a sec :/

OpenStudy (angelwings996):

okay

OpenStudy (angelwings996):

Oh, would the answer be the first one? I did y = x in all of the graphs and it seems like the one that reflects the best is the first one

hero (hero):

Yes

OpenStudy (angelwings996):

I got

OpenStudy (angelwings996):

@Hero

hero (hero):

I think you're confusing what @saifoo.khan showed you. You have no idea how the actual graph looks. The only important thing is that the reflected point is equidistant from y = x with respect to the original point.

OpenStudy (angelwings996):

Not really because I just connected the dots together and got the first one, then did the y = x like you said then connected those lines that are reflected and got the answer
