Question 492304
We can use the distance formula to find the distance.

{{{sqrt((x2 - x1)^2 + (y2 - y1)^2 )}}}
{{{sqrt((2 - -7)^2 + (1 - 11)^2 )}}}
{{{sqrt((9)^2 + (10)^2 )}}}
{{{sqrt(181 )}}}
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)
