Well u have to make sure your school pops up

so no not really I guess

Step-by-step explanation:

The given data is
time (h):    2   4   6   8
gallons:  43 36 29 22

A graph of the data shows a linear relationship.
Therefore in slope-intercept form, let
(y - 29)/(x - 6) = m
where m = the slope of the straight line.

Calculate the slope.
m = (43 - 22)/(2 - 8) = -7/2
