Answer:
y=5x+3
Step-by-step explanation:
I learned it in school :)
<span>Table
Bottles Price($)
3 78
6 156
9 234
From that you can find the unit price: 78 / 3 = 156 / 6 = 234 / 9 = 26.
That means that the unit rate of this fragance is $26.
If you call x the number of bottles the equation is
Price = unit rate * number of bottles = 26x.
Now compare this information with that on your graph to compare the unit rates.
This can help you fo find the unit rate in from your grpah: the unit rate is the slope of the line =
[change in y-coordinate] / [change in the x-coordinate]

6 m.p.g if that's the type of question your referring to...
Since there are three variables and three constants you add like terms.
3(x+15) = 3x + 40
