Algebra.Com's Answer #315554 by mananth(16946)![]() ![]() You can put this solution on YOUR website! y = -3x + 4.................1 \n" ); document.write( "6y + 18x = 24 \n" ); document.write( "6y=-18x+24 \n" ); document.write( "/6 \n" ); document.write( "y=-3x+4......................2\r \n" ); document.write( "\n" ); document.write( "Both the lines are having same slope -3 and same y intercept +4 \n" ); document.write( "so the lines coincide. ( they are one and the same lines)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "when x= 0 y= 4 (0,4) \n" ); document.write( "when y = 0 x= 1.33(1.33,0)\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "All the points on the line are the solutions to both the equations. So, the system of equations has infinite number of solutions. \n" ); document.write( "So, the system of equations is consistent and the equations are dependent. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
