You can put this solution on YOUR website!
You choose an x, solve for y.
\n" ); document.write( "This is the equation of a straight line so you only need two points to graph it.
\n" ); document.write( "So when $\"x=0\"$ ,
\n" ); document.write( " $\"5%280%29%2B3y=12\"$
\n" ); document.write( " $\"3y=12\"$
\n" ); document.write( " $\"y=4\"$
\n" ); document.write( "So ( $\"0\"$ , $\"4\"$ ) is a point on the line.
\n" ); document.write( "When $\"x=1\"$ ,
\n" ); document.write( " $\"5%281%29%2B3y=12\"$
\n" ); document.write( " $\"5%2B3y=12\"$
\n" ); document.write( " $\"3y=7\"$
\n" ); document.write( " $\"y=7%2F3\"$
\n" ); document.write( "( $\"1\"$ , $\"7%2F3\"$ )
\n" ); document.write( "Plot those two points and draw the straight line.
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "You could also use the x and y intercepts.
\n" ); document.write( "When $\"x=0\"$ ,
\n" ); document.write( " $\"5%280%29%2B3y=12\"$
\n" ); document.write( " $\"3y=12\"$
\n" ); document.write( " $\"y=4\"$
\n" ); document.write( "( $\"0\"$ , $\"4\"$ )
\n" ); document.write( "When $\"y=0\"$ ,
\n" ); document.write( " $\"5x%2B3%280%29=12\"$
\n" ); document.write( " $\"5x=12\"$
\n" ); document.write( " $\"x=12%2F5\"$
\n" ); document.write( "( $\"12%2F5\"$ , $\"0\"$ )
\n" ); document.write( ".

\n" ); document.write( ".
