Algebra.Com's Answer #439941 by Edwin McCravy(20060)![]() ![]() You can put this solution on YOUR website! The first coordinate of (-3,___) is given. The first coordinate \n" ); document.write( "is what you substitute for x in order to get the value of y, \n" ); document.write( "which is the second coordinate. So instead of x in the equation\r \n" ); document.write( "\n" ); document.write( "y = 4 - 3x\r \n" ); document.write( "\n" ); document.write( "we write (-3) in place of x, like this:\r \n" ); document.write( "\n" ); document.write( "y = 4 - 3(-3)\r \n" ); document.write( "\n" ); document.write( "and then simplify\r \n" ); document.write( "\n" ); document.write( "y = 4 + 9\r \n" ); document.write( "\n" ); document.write( "y = 13\r \n" ); document.write( "\n" ); document.write( "And that value of y is the second coordinate and so the \n" ); document.write( "answer is:\r \n" ); document.write( "\n" ); document.write( "(-3,13)\r \n" ); document.write( "\n" ); document.write( "Edwin \n" ); document.write( " \n" ); document.write( " |
