Algebra.Com's Answer #95965 by stanbon(75887) ![]() You can put this solution on YOUR website! solve and graph the following equation and interpet the result: \n" ); document.write( "2x-3y=6 and 2x+y=-10. \n" ); document.write( "---------------------- \n" ); document.write( "solve both equation for \"y\": \n" ); document.write( "y = (2/3)x-2 \n" ); document.write( "y = -2x-10 \n" ); document.write( "------------- \n" ); document.write( "Graph y = (2/3)x-2 \n" ); document.write( "If x = 0, y = -2 \n" ); document.write( "If x = 3, y = 0 \n" ); document.write( "Plot the two points and draw a line thru them. \n" ); document.write( " \n" ); document.write( "------------------- \n" ); document.write( "Graph y = -2x-10 \n" ); document.write( "If x = 0, y = -10 \n" ); document.write( "If x = 1, y = -12 \n" ); document.write( "Plot the two points and draw a line thru them. \n" ); document.write( " \n" ); document.write( "--------------------- \n" ); document.write( "Graphing them on the same set of axes you might see \n" ); document.write( "the lines cross at (-3,-4); this is the solution for \n" ); document.write( "the system of two equations. It is the common solution. \n" ); document.write( "----------------- \n" ); document.write( " \n" ); document.write( "==================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
