You can put this solution on YOUR website!
You need two points on the line in order to graph it.

\n" ); document.write( "Plug-in two different x values in the equation to get their y values, like so:

\n" ); document.write( "y = (600/5)
\n" ); document.write( "y = 120
\n" ); document.write( "p1 = (0, 120)
\n" ); document.write( "---
\n" ); document.write( "Point p2, use x=50 (using x=50 makes y a whole number):
\n" ); document.write( "y = (-8/5)(50) + (600/5)

\n" ); document.write( "p2 = (50, 40)
\n" ); document.write( "---
\n" ); document.write( "Now draw a line between points p1 and p2 to graph the equation.
\n" ); document.write( "The line extends infinitely beyond both points.
