Algebra.Com's Answer #328071 by MathLover1(20850) You can put this solution on YOUR website! We take a point p= (x,y) the the result of rotation p 90 clockwise about the origin is a new point p'=(x',y')= (-y, x).\r \n" ); document.write( "\n" ); document.write( "ex:\r \n" ); document.write( "\n" ); document.write( "In the case of p=(1,0) the new point is p'= (0, -1)\r \n" ); document.write( "\n" ); document.write( "so, in your case it will be:\r \n" ); document.write( "\n" ); document.write( "for p=(-2,4) the new point is p'= (4, -(-2))=(4,2) \n" ); document.write( " |
