Determine k so that the line through (k+2,k) and (3,2) has a slope of 3.
\n" ); document.write( ".
\n" ); document.write( "Since slope is defined as:
\n" ); document.write( "(y2 - y1)/(x2 - x1)
\n" ); document.write( "we have
\n" ); document.write( "3 = (2-k)/(3-(k+2))
\n" ); document.write( "3 = (2-k)/(3-k-2)
\n" ); document.write( "3 = (2-k)/(1-k)
\n" ); document.write( "3(1-k) = (2-k)
\n" ); document.write( "3-3k = 2-k
\n" ); document.write( "3 = 2+2k
\n" ); document.write( "1 = 2k
\n" ); document.write( "1/2 = k \n" ); document.write( "

\n" );
