Answer:
The situation you are describing can be written as y=2x, or in this case t=2f, for every fragrance purchased there are 2 ounces of lotion that are given. Since the ounces of fragrance are not shown in this question, we can only make the graph on the ounces of lotion for every fragarance purchased. The points of the graph represent that for every fragrance bought, there is twice the amount of that in ounces of lotion. In summary, the rule is t=2f where t would equal purchases of fragrance and f would equal the ounces of lotion.
(If there is any more you would like to add to the question I can answer that.)
The equation of the line is given as 
A straight line equation is given in the form
where 
is the gradient and 
is the y-interest.
We need to rearrange to make 
the subject.
⇒ from here we can read the gradient and the y-intercept. The gradient,
