Question 1164793
distance is sqrt (differnce between each x or each y^2 added)
this is sqrt (2^2+1^2) or sqrt 5 or 2.236 (2.24 is the answer). With distance, unlike slope, the order does not matter, since the result is squared.

The midpoint is the average of the two x values (-1) and the average of the two y-values (9.5), so it is (-1. 9.5)
