Your idea?

OpenStudy (jurynee):

OpenStudy (loser66):

Where are you stuck?

OpenStudy (jurynee):

im stuck when it says radius that just confused me

OpenStudy (loser66):

Yes, it is a distraction. Ignore it, just focus on C (-2,1) and reflect it about x-axis. What do you get?

OpenStudy (jurynee):

(-2,-1)
