We can use the distance formula to find the distance.\r

\n" ); document.write( " $\"sqrt%28%282+-+-7%29%5E2+%2B+%281+-+11%29%5E2+%29\"$
\n" ); document.write( " $\"sqrt%28%289%29%5E2+%2B+%2810%29%5E2+%29\"$
\n" ); document.write( " $\"sqrt%28181+%29\"$
\n" ); document.write( "For the midpoint, we will use the midpoint formula.
