Are these three points collinear?\r
\n" ); document.write( "\n" ); document.write( "\"%288-4%29%2F%284-12%29=%284-1.5%29%2F%2812-17%29\"
\n" ); document.write( "\"4%2F%28-8%29=2.5%2F%28-5%29\"
\n" ); document.write( "\"-1%2F2=-1%2F2\"
\n" ); document.write( "Yes, common slope using these points.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Pick any of the three points and use now known slope, and fill-in the point-slope form equation. Do whatever you want with it.\r
