Algebra.Com's Answer #27952 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! The easiest way to see this is to merely graph it. \n" ); document.write( "Since you are rotating it counterclockwise 90 degrees, merely tilt your head \n" ); document.write( "90 degrees CLOCKWISE and then tell me the coordinates of C as it appears to you now...yes, that's it...(2, 3)! \n" ); document.write( " |
