slope for first two is change in y/change in x
\n" ); document.write( "8-(-7)/-2-2
\n" ); document.write( "8/-4=-2\r
\n" ); document.write( "\n" ); document.write( "second and third must have a slope of -2
\n" ); document.write( "k-1/8-(-2)\r
\n" ); document.write( "\n" ); document.write( "(k-1)/10 equals -2
\n" ); document.write( "-20=k-1
\n" ); document.write( "k=-19\r
\n" ); document.write( "\n" ); document.write( "(8,-19)\r
\n" ); document.write( "\n" ); document.write( "first and third should be the same
\n" ); document.write( "-19-(-7)/8-2\r
\n" ); document.write( "\n" ); document.write( "-12/6 slope is -2\r
