\n" ); document.write( "Looks like it but to verify get the equation of the line using the endpoints.
\n" ); document.write( " $\"m=%281-7%29%2F%286-%28-3%29%29=-6%2F9=-2%2F3\"$
\n" ); document.write( " $\"y-1=-%282%2F3%29%28x-6%29\"$
\n" ); document.write( " $\"3y-3=-2%28x-6%29\"$
\n" ); document.write( " $\"3y-3=-2x%2B12\"$
\n" ); document.write( " $\"2x%2B3y=15\"$
\n" ); document.write( "Now you can check the middle point.
\n" ); document.write( " $\"2%280%29%2B3%285%29=15\"$
\n" ); document.write( " $\"15=15\"$
\n" ); document.write( "True, so they are collinear.
