Midpoint formula : (x1 + x2) / 2, (y1 + y2)/2
(-6,3)....x1 = -6 and y1 = 3
(4,-2)...x2 = 4 and y2 = -2
now sub
m = (-6 + 4) / 2, (3 - 2) / 2
m = (-2/2, 1/2)
m = (- 1, 0.5) <==
The unit cost for each shirt is $6.50

Answer:
No, it's not a one to one function
Step-by-step explanation:
In one to one function, the function is either increasing or decreasing. Also, in this type of function, the same values can not be assigned to two different domain elements.
In this case, distance from city C and City E are both 1195 miles from city M.
Thus defaults the law of one to one function.
Therefore it's not one to one function.
