Given:
The graph of linear function.
To find:
The slope intercept form of the linear equation from the given graph.
Solution:
The slope intercept form of a linear function is:

From the given graph it is clear that the graph passes through the points (1,300) and (4,800).
The equation of line is




Adding 300 on both sides, we get



Therefore, the required equation is
.
Write the equation out: (total cost: 0.35C[per carton] + 75[delivery charge]) ≤ 500. Subtract 75 on both sides and it would be: 0.35C ≤ 425. Divide 0.35 on both sides and you'll get C ≤ 1214. Therefore, the maximum # of cartons that Elvira can buy is 1214 cartons of milk.
~For this problem, you need to divide.
~The easy way that I think might help you is if you change the fraction into a decimal.
Now divide $8.47 by 0.875
