The answer is about 60ish. Hope this helped. :-)
M = (7,6)
Step-by-step explanation:
formula to find mindpoint is

(4,2) = (x1, y1)
(10,10) = (x2,y2)
now substitute those into the formula!

now solve for x & y !!


so now that we have solved for x & y put it in point form and your done !!
point for is (x,y)
and thanks why the Midpoint is (7,6)
