Algebra.Com's Answer #253363 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! In my homework I need to graph linear systems and estimate the solution for this equation:\r \n" ); document.write( "\n" ); document.write( "y= -3x+2 \n" ); document.write( "y= 2x-3 \r \n" ); document.write( "\n" ); document.write( "My answer for where the two lines crossed was (-1,-3) but I don't know if that's right. \n" ); document.write( "------------------- \n" ); document.write( "Put that x/y pair into each equation and see if your \"solution\" \n" ); document.write( "is really a solution. \n" ); document.write( "--- \n" ); document.write( "Putting it into the 1st equation you \n" ); document.write( "would get -3 = -3(-1) = 2 \n" ); document.write( "-3 = 3+2 \n" ); document.write( "That is wrong so (-1,-3) is not the correct solution. \n" ); document.write( "---- \n" ); document.write( " \n" ); document.write( "--- \n" ); document.write( "I think (1,-1) is the correct answer. \n" ); document.write( "Checking: \n" ); document.write( "y = -3x+2 \n" ); document.write( "-1 = -3*1+2 \n" ); document.write( "-1 = -1 \n" ); document.write( "---- \n" ); document.write( "y = 2x-3 \n" ); document.write( "-1 = 2*1-3 \n" ); document.write( "-1 = 2-3 \n" ); document.write( "-1 = -1 \n" ); document.write( "------- \n" ); document.write( "The pair 1,-1 checks out in both equations, \n" ); document.write( "so that pair is the solution. \n" ); document.write( "================================ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
