Use the slope-intercept form $\"y+=+mx+%2B+b\"$
\n" ); document.write( " $\"-3+=+m%2A7+%2B+2\"$
\n" ); document.write( " $\"7m+=+-5\"$
\n" ); document.write( " $\"m+=+-%285%2F7%29\"$
\n" ); document.write( "The whole equation is
\n" ); document.write( " $\"y+=+-%285%2F7%29x+%2B+2\"$
\n" ); document.write( "In standard form:
\n" ); document.write( " $\"%285%2F7%29x+%2B+y+-+2+=+0\"$
\n" ); document.write( " $\"5x+%2B+7y+-+14+=+0\"$ answer
\n" ); document.write( "check:
\n" ); document.write( "does the line go through (7,-3)?
\n" ); document.write( " $\"5%2A7+%2B+7%2A%28-3%29+-+14+=+0\"$
\n" ); document.write( " $\"35+-+21+-+14+=+0\"$
\n" ); document.write( " $\"35+-+35+=+0\"$
\n" ); document.write( " $\"0+=+0\"$
\n" ); document.write( "OK \n" ); document.write( "
