If the general form of one equation
\n" ); document.write( "looks like:
\n" ); document.write( " $\"+y+=+m%2Ax+%2B+b%5B1%5D+\"$ ,
\n" ); document.write( "then, for the other line to be perpendicular
\n" ); document.write( "to this one, the equation must look like:
\n" ); document.write( " $\"+y+=+%28-1%2Fm%29%2Ax+%2B+b%5B2%5D+\"$
\n" ); document.write( "--------------------------------------
\n" ); document.write( " $\"+b%5B1%5D+\"$ and $\"+b%5B2%5D+\"$ are y-intercepts
\n" ); document.write( "-----------------
\n" ); document.write( "For example:
\n" ); document.write( "For the 1st line:
\n" ); document.write( " $\"+m+=+-1%2F2+\"$
\n" ); document.write( " $\"+b%5B1%5D+=+7+\"$
\n" ); document.write( "-----------------
\n" ); document.write( "For the 2nd line:
\n" ); document.write( " $\"+-1%2Fm+=+-1%2F%28-1%2F2%29+\"$
\n" ); document.write( " $\"+-1%2Fm+=+2+\"$
\n" ); document.write( " $\"+b%5B2%5D+=+1+\"$
\n" ); document.write( "----------------------
\n" ); document.write( "Here's the lines:
\n" ); document.write( " $\"+y+=+-%281%2F2%29%2Ax+%2B+7+\"$
\n" ); document.write( " $\"+y+=+2x+%2B+1+\"$
\n" ); document.write( "-----------------------
\n" ); document.write( "Here are the plots:
\n" ); document.write( " $\"+graph%28+600%2C+600%2C+-5%2C+18%2C+-5%2C+18%2C+-%281%2F2%29%2Ax+%2B+7%2C+2x+%2B+1+%29+\"$
\n" ); document.write( " \n" ); document.write( "
