find the value of k if line AB has a slope of -2, when A(-2,-5) and B(k,7)?
\n" ); document.write( "**
\n" ); document.write( "slope=m=-2=∆y/∆x=(y1-y2)/(x1-x2)=(7+5)/(k+2)
\n" ); document.write( "-2=12/(k+2)
\n" ); document.write( "-2k-4=12
\n" ); document.write( "-2k=16
\n" ); document.write( "k=-8
\n" ); document.write( "
\n" );
