Step-by-step explanation:

You would have eaten 1/6 of the serving.
To find where graph is intercepting x and y axis all we have to do is to calculate what is value of x when y = 0 (x intercept) and what value of y is when x = 0 (y intercept)
1) x = 0
-3y = 9
y = -3
2) y = 0
x = 9/2
Graph is bellow.
