$2.52 x 8 (8 per half gallons is 4 gallons) = $20.16
Answer:
The graph in the attached figure
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>
In this problem the given line represent a proportional relationship, because passes through the origin
we have
---> the constant of proportionality k is equal to the slope
substitute
The linear equation is
![y=\frac{4}{3}x](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B4%7D%7B3%7Dx)
To draw a line we need two points
we have (0,0)
To find the other point
assume x=3 and substitute in the equation to solve for y
![y=\frac{4}{3}(3)=4](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B4%7D%7B3%7D%283%29%3D4)
so
The other point is (3,4)
using a graphing tool
Plot the points (0,0) and (3,4)
To graph the line join the points
see the attached figure
I'm sure that the answer should be b
