10y+15x=20
\n" ); document.write( "Let x=0 and solve for y
\n" ); document.write( "10y+15(0)=20
\n" ); document.write( "10y+0=20
\n" ); document.write( "10y=20
\n" ); document.write( "10y/10=20/10
\n" ); document.write( "y=2 Plot (0,2)
\n" ); document.write( ":
\n" ); document.write( "Let x=2 and solve for y
\n" ); document.write( "10y+15(2)=20
\n" ); document.write( "10y+30=20
\n" ); document.write( "10y+30-30=20-30
\n" ); document.write( "10y=-10
\n" ); document.write( "10y/10=-10/10
\n" ); document.write( "y=-1 Plot (2,-1)
\n" ); document.write( "For lines you only need to plot two points unless otherwise specified. If you need to plot more, let x be even numbers to avoid fractions.
\n" ); document.write( "Connect the two points and you have a line that looks like:
