Question 185665
If C = total cost and S = represent the amount of sugar (in tons).

We can write a linear equation:

C(S) = $6525 + $225(S)

Let C(S) = y and S = x in the form of points that must be graphed on the coordinate plane.

One point is (S,C(S)) = (x,y).

Set up a table for S and C(S).  

Select different values for S to plug into the equation above.

I would select 4 different values for S to plug into the equation.
Simplify equation for each value to get 4 points that you will graph on the coordinate plane.

This is a linear equation.  The word linear comes from the word line.  So, your graph will be a straight line.

Does this help?
