To find the cost per serving, we can use the formula for finding the slope of a line:
slope = (y2 - y1) / (x2 - x1)
In this case, let's assign the number of servings as the x-values and the cost as the y-values.
Let's use the points (3, 18) and (10, 60) as (x1, y1) and (x2, y2), respectively.
Plugging in the values, we have:
slope = (60 - 18) / (10 - 3)
= 42 / 7
= 6
Therefore, the cost per serving is $6.
slope = (y2 - y1) / (x2 - x1)
