The general form is:
\n" ); document.write( " $\"+y+=+m%2Ax+%2B+b+\"$
\n" ); document.write( "where $\"+m+\"$ is the slope
\n" ); document.write( "and $\"+b+\"$ = the y-intercept
\n" ); document.write( "---------------------------
\n" ); document.write( "( -2.4 )
\n" ); document.write( " $\"+4+=+m%2A%28-2%29+%2B+b+\"$
\n" ); document.write( " $\"+b+=+2m+%2B+4+\"$
\n" ); document.write( "------------------
\n" ); document.write( "This is another linear equation
\n" ); document.write( "I'll just pick any $\"+m+\"$ and
\n" ); document.write( "find $\"+b+\"$
\n" ); document.write( " $\"+m+=+-4+\"$
\n" ); document.write( " $\"+b+=+2%2A%28-4%29+%2B+4+\"$
\n" ); document.write( " $\"+b+=+-4+\"$
\n" ); document.write( "------------
\n" ); document.write( "So, my equation is:
\n" ); document.write( " $\"+y+=+-4x+%2B+-4+\"$
\n" ); document.write( "This is just one possible equation,
\n" ); document.write( "but that's all they wanted
\n" ); document.write( "-------------------
\n" ); document.write( "check:
\n" ); document.write( "Does it go through ( -2,4 )?
\n" ); document.write( " $\"+4+=+-4%2A%28-2%29+-+4+\"$
\n" ); document.write( " $\"+4+=+8+-+4+\"$
\n" ); document.write( " $\"+4+=+4+\"$
\n" ); document.write( "OK \n" ); document.write( "

\n" );
