The slope is ( change in y ) / ( change in x )
\n" ); document.write( "Let slope = \"+m+\"
\n" ); document.write( "\"+m+=+%28+9+-+1+%29+%2F+%28+-10+-+6+%29+\"
\n" ); document.write( "\"+m+=+8+%2F+%28-16%29+\"
\n" ); document.write( "\"+m+=+-1%2F2+\"
\n" ); document.write( "----------------
\n" ); document.write( "Use the general point-slope formula
\n" ); document.write( "\"+%28+y+-+1+%29+%2F+%28+x+-+6+%29+=+-1%2F2+\"
\n" ); document.write( "\"+y+-+1+=+-%281%2F2%29%2A%28+x+-+6+%29+\"
\n" ); document.write( "\"+y+-+1+=+-%281%2F2%29%2Ax+%2B+3+\"
\n" ); document.write( "\"+y+=+-%281%2F2%29%2Ax+%2B+4+\"
\n" ); document.write( "The answer is (a)\r
