To graph equations in standard form as these are, I think the easiest way to graph is the TWO-Intercept Method. Find the intercepts for each equation, and graph them:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x+y=13\r
\n" ); document.write( "\n" ); document.write( "If x=0, then y=13
\n" ); document.write( "If y=0, then x=13\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x-y=5
\n" ); document.write( "If x=0, then y=-5
\n" ); document.write( "If y=0, then x=5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now graph these points and connect the dots!!! It should look like this:\r
\n" ); document.write( "\n" ); document.write( "\"graph%28300%2C300%2C+-15%2C15%2C+-15%2C15%2C+13-x%2Cx-5%29\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The lines intersect in a single point, so the system is said to be \"Independent\". The solution is the point (9,4).\r
