Shipments of fabric to each plant vary per week as follows: plant a, 200 units; plant b, 400 units; plant c, 300 units; plant d, 300 units; and plant e, 200 units. What is the optimal location for the fabric plant?.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

x + 4/7
