Step-by-step explanation:
Given
![2 cans = 10ft\ by\ 12ft](https://tex.z-dn.net/?f=2%20cans%20%3D%2010ft%5C%20by%5C%2012ft)
Required
Graph the relationship between both parameters
First, calculate the area;
![Area = 10ft * 12ft](https://tex.z-dn.net/?f=Area%20%3D%2010ft%20%2A%2012ft)
![Area = 120ft^2](https://tex.z-dn.net/?f=Area%20%3D%20120ft%5E2)
This implies that: (2, 120) i.e. 2 cans for 120ft^2.
So we have:
(0,0) and (2,120)
(0,0) implies that: 0 cans for 0 square feet
Calculate the slope:
![m = \frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D)
![m = \frac{120 - 0}{2-0}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B120%20-%200%7D%7B2-0%7D)
![m = \frac{120 }{2}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B120%20%7D%7B2%7D)
![m = 60](https://tex.z-dn.net/?f=m%20%20%3D%2060)
The equation is:
![y = m(x - x_1) + y_1](https://tex.z-dn.net/?f=y%20%3D%20m%28x%20-%20x_1%29%20%2B%20y_1)
So, we have:
![y = 60 * (x - 0) + 0](https://tex.z-dn.net/?f=y%20%3D%2060%20%2A%20%28x%20-%200%29%20%2B%200)
![y = 60 * (x )](https://tex.z-dn.net/?f=y%20%3D%2060%20%2A%20%28x%20%29)
![y = 60 x](https://tex.z-dn.net/?f=y%20%3D%2060%20x)
