Step-by-step explanation:
# bags of # bushels Cost $
seeds
0 0 0
1 5 1 × 120 = 120
2 9 2 × 120 = 240
3 12 3 × 120 = 360
Pair # bags of seeds with cost
# bags of Cost $
seeds
0 0
1 120
2 240
3 360
Since the unit cost is constant, this is a linear function, which has the general form
![y=mx+b](https://img.qammunity.org/2021/formulas/mathematics/middle-school/yj5waqmoy4i54laybzhhshd88hyo5w5rj5.png)
Where m is the slope (the unit cost) and b is the y-intercep (the value when the number of bags is zero).
Thus the curve is modeled by the function:
![C(x)=120x](https://img.qammunity.org/2021/formulas/business/middle-school/my2dzqrxcm45121nbm73c4vck9a6wqrvpt.png)
Where C(x) is the cost and x is the number of bag of seeds.
To draw the curve, you can use the four points:
- (0,0)
- (1, 120)
- (2, 240)
- (3,360)
