You can put this solution on YOUR website!
(1) You have to get the given equation into
\n" ); document.write( "the form $\"y+=+mx+%2B+b\"$ , where $\"m\"$ is the slope
\n" ); document.write( "Any line parallel to the given line
\n" ); document.write( "will have the same slope.
\n" ); document.write( " $\"3x+%2B+6y+=+-12\"$
\n" ); document.write( " $\"6y+=+-3x+-+12\"$
\n" ); document.write( " $\"y+=+-%281%2F2%29%2Ax+-+2\"$
\n" ); document.write( " $\"m+=+-1%2F2\"$
\n" ); document.write( "Now I know the general form I want is
\n" ); document.write( " $\"y+=+-%281%2F2%29%2Ax+%2B+b\"$
\n" ); document.write( "Now plug in (4,-2) to find $\"b\"$
\n" ); document.write( " $\"-2+=+-%281%2F2%29%2A4+%2B+b\"$
\n" ); document.write( " $\"b+=+-2+%2B+2\"$
\n" ); document.write( " $\"b+=+0\"$
\n" ); document.write( "The solution is $\"y+=+-%281%2F2%29%2Ax\"$
\n" ); document.write( "(2)
\n" ); document.write( "Start with the general form
\n" ); document.write( " $\"y+=+mx+%2B+b\"$
\n" ); document.write( "From the given info, $\"m\"$ can be anything, so I pick $\"m+=+1\"$
\n" ); document.write( "Given: (3,5)
\n" ); document.write( " $\"5+=+1%2A3+%2B+b\"$
\n" ); document.write( " $\"b+=+2\"$
\n" ); document.write( " $\"y+=+x+%2B+2\"$ is one possible answer \n" ); document.write( "

\n" );
