You can put this solution on YOUR website!
1.)
\n" ); document.write( "y = 4x - 7
\n" ); document.write( "y = 3x + 2\r
\n" ); document.write( "\n" ); document.write( "This ahs one solution. The slopes are different and the y intercepts are not the same. So trhey will intersect\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2.)
\n" ); document.write( "y = 3x - 6
\n" ); document.write( "y = 3x + 1\r
\n" ); document.write( "\n" ); document.write( "the slopes of the lines are same and the y intercepts are different. So zero solution. As the lines will never meet.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3.)
\n" ); document.write( "-2x + 3y = 2
\n" ); document.write( "6y - 4X = 4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "When you multiply the first equation by 2 you find that both lines are identical. same slope , same intercept. It means that the lines coincide and has innumerable solutions\r
