Answer:
See below.
Step-by-step explanation:
First, it's obviously a line so the equation is a linear equation.
In order to find a linear equation, we first need the slope and the y-intercept. Recall the slope-intercept form:
, where m is the slope and b is the y-intercept.
We already know the point (0,3) which is the y-intercept. Thus, b=3.
To find the slope, use the slope formula:

Thus, the equation is:

4.40÷20=0.22

All you do is 1x+2x+5x=8x then you turn 4 s into pints. 1 gallon equals 4 pints 4*4=16 pints. 8x=16 x=2. Then you multiply everything by 2
1*2=2
2*2=4
2*5=10
