You can put this solution on YOUR website!
In order plot a graph, we want the equation in the slope/intercept form, y = mx + b
\n" ); document.write( ":
\n" ); document.write( "2x + 5y = 12
\n" ); document.write( "5y = -2x + 12
\n" ); document.write( "divide both sides by 5
\n" ); document.write( "y = \"-2%2F5\"x + \"12%2F5\"
\n" ); document.write( "this will work OK using decimals
\n" ); document.write( "y = -.4x + 2.4
\n" ); document.write( ":
\n" ); document.write( "Choose a couple values for x and find y:
\n" ); document.write( "x = -3
\n" ); document.write( "y = -.4(-3) + 2.4
\n" ); document.write( "y = +1.2 + 2.4
\n" ); document.write( "y = 3.6
\n" ); document.write( ":
\n" ); document.write( "x = +3
\n" ); document.write( "y = -.4(3) + 2.4
\n" ); document.write( "y = -1.2 + 2.4
\n" ); document.write( "y = + 1.2
\n" ); document.write( ":
\n" ); document.write( " x | y
\n" ); document.write( "--------
\n" ); document.write( "-3 | 3.6
\n" ); document.write( "+3 | 1.2
\n" ); document.write( "Should look like this
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-5%2C+8%2C+-5%2C+5%2C+-.4x%2B2.4%29+\"
