We can use the distance formula to find the distance.
sqrt%28%28x2+-+x1%29%5E2+%2B+%28y2+-+y1%29%5E2+%29
sqrt%28%282+-+-7%29%5E2+%2B+%281+-+11%29%5E2+%29
sqrt%28%289%29%5E2+%2B+%2810%29%5E2+%29
sqrt%28181+%29
For the midpoint, we will use the midpoint formula.
M = ( (x1 + x2)/2, (y1 + y2)/2)
M= ((-7 +5)/2, (11 +1)/2)
M= (-1, 6)
