9x+3y=6
\n" ); document.write( "since this is a linear equation( an equation that produces a straight line) we only need to enter two values on the graph.
\n" ); document.write( "the easiest two to calculate ate when y=0 and when x=0
\n" ); document.write( "when x=0 we get 3y=6 so y=2
\n" ); document.write( "when y=0 we get 9x=6 so x=6/9 or 2/3
\n" ); document.write( "we can also divide the whole equation by 3
\n" ); document.write( "3x+y=2
\n" ); document.write( "which would produce the same line.
\n" ); document.write( "we can also solve for x=1 and y =1
\n" ); document.write( "if x=1 then we have
\n" ); document.write( "9x+3y=6
\n" ); document.write( "9+3y=6
\n" ); document.write( "subtract 9 from both sides
\n" ); document.write( "3y=-3
\n" ); document.write( "y=-1
\n" ); document.write( "or
\n" ); document.write( "3x+y=2
\n" ); document.write( "3+y=2
\n" ); document.write( "subtract 3 from both sides
\n" ); document.write( "y=-1\r
\n" ); document.write( "\n" ); document.write( "if y=1 we have
\n" ); document.write( "9x+3y=6
\n" ); document.write( "9x+3=6
\n" ); document.write( "subtract 3 from both sides
\n" ); document.write( "9x=3
\n" ); document.write( "x=1/3
\n" ); document.write( "3x+y=2
\n" ); document.write( "3x+1=2
\n" ); document.write( "subtract 1 from both sides
\n" ); document.write( "3x=1
\n" ); document.write( "x=1/3\r
\n" ); document.write( "\n" ); document.write( "I would plot the two points with just whole numbers\r
