Answer:
(2,4)
Step-by-step explanation:
What the formula basically does is calculate the "average" x and y. You probably know how to calculate the average of a set of numbers.
The x coordinates are 1 and 3, their average is 2. You get that by adding them (=4) and dividing by 2. (=2)
The y coordinates are 3 and 5, their average is 4. You get that by adding them (=8) and dividing by 2. (=4)
So, in formula:
[tex]M = ( \frac{1+3}2 , \frac{3+5}2) = (2,4)[/tex]
