Step-by-step explanation:
5.
a.
Variable y is independent
Variable x is dependent
b.
f_f(x)=0.063*x+0 . Computer's best guess is this given the points. Needing further information. [DO NOT TRUST THIS ANSWER] (for b.)
c.
Unit rate = a rate for one of something. Calculate how much y, cost increases for one fluid ounces, x.
d.
Cost, y = 2.
6.
y = [UNABLE TO FIND]
Let's say user chooses a random area of 6. 6 = 1/2bh. We know, in accordance to the table that the height, x correlating to area, 6 is 2.
1/2 * 2 = 1
1 * b = 6, b = 6.
7.
y = 64x
In accordance to the graph, an increase of 128 miles takes 2 hours. That means in 1 hour, there is an increase of 64 miles.
