A manufacturing plant earned 80$ per man-hour of labor when it opened. Each year , the plant earns an additional 6% per man-hour. Which expression gives the amount the plant earned per man-hour labor 3 years after it opened?

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)

tangent
