You can put this solution on YOUR website!
20 +4y = 2x + 40
\n" ); document.write( ".
\n" ); document.write( "Get into slope-intercept form.
\n" ); document.write( "y = mx +b
\n" ); document.write( ".
\n" ); document.write( "4y = 2x +20
\n" ); document.write( ".
\n" ); document.write( "divide by 4
\n" ); document.write( ".
\n" ); document.write( "y = 2/4*x +5
\n" ); document.write( ".
\n" ); document.write( "y = 1/2*x + 5
\n" ); document.write( ".
\n" ); document.write( "m = slope = 1/2
\n" ); document.write( ".
\n" ); document.write( "y-intercept = (0,5)
\n" ); document.write( ".
\n" ); document.write( "x-intercept is where y=0, so set y=0 and solve for x.
\n" ); document.write( ".
\n" ); document.write( "0 = 1/2*x +5
\n" ); document.write( "1/2*x = -5
\n" ); document.write( "x = -10
\n" ); document.write( ".
\n" ); document.write( "x-intercept = (-10,0)
\n" ); document.write( ".
