2x + 5y= 10
\n" ); document.write( "50x+ 125y= 100
\n" ); document.write( "multiply top by -25
\n" ); document.write( "-50x-125y=-2500, add
\n" ); document.write( "0=-2400. no solution. Lines are parallel.\r
\n" ); document.write( "\n" ); document.write( "Can write as y=mx+b
\n" ); document.write( "5y=-2x+10 first one
\n" ); document.write( "y=-(2/5)x+2, dividing both sides by 5\r
\n" ); document.write( "\n" ); document.write( "125y=-50x+100
\n" ); document.write( "y=(-50/125)x+(100/125) after dividing both sides by 125
\n" ); document.write( "y=(-2/5)x+(4/5)
\n" ); document.write( "both have the same slope but different y-intercepts. That is the definition of parallel lines.
\n" ); document.write( "
\n" );
