Explanation:
Given
![2 cans = 10ft\ by\ 12ft](https://img.qammunity.org/2022/formulas/mathematics/college/ggk0et7vtu5iobec37wbh7ejfphznncrv8.png)
Required
Graph the relationship between both parameters
First, calculate the area;
![Area = 10ft * 12ft](https://img.qammunity.org/2022/formulas/mathematics/college/vlzei7jah98o2s3w6x5g3sqqt22t6j0u7d.png)
![Area = 120ft^2](https://img.qammunity.org/2022/formulas/mathematics/college/p9w7n9wof2znon1sfqle77lempyob4w9tq.png)
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 = (y_2 - y_1)/(x_2 - x_1)](https://img.qammunity.org/2022/formulas/mathematics/college/i1pa2mybgkt3dkd7j6tklhm5t9tvmo4g5v.png)
![m = (120 - 0)/(2-0)](https://img.qammunity.org/2022/formulas/mathematics/college/xcoucp0q7ftewkwk9ful7qzuv4mpcz8s7h.png)
![m = (120 )/(2)](https://img.qammunity.org/2022/formulas/mathematics/college/osskykpfijtigru1urnw7eh5nbq6ggv56u.png)
![m = 60](https://img.qammunity.org/2022/formulas/mathematics/college/fgox6g0quafmlicw8v88ya95cti79eppmo.png)
The equation is:
![y = m(x - x_1) + y_1](https://img.qammunity.org/2022/formulas/mathematics/college/q3fz2j2j3y666k3ykrf0me9rxopd59ekuj.png)
So, we have:
![y = 60 * (x - 0) + 0](https://img.qammunity.org/2022/formulas/mathematics/college/fzhlfsjejndzqjou8xawr6xquugv0hhzll.png)
![y = 60 * (x )](https://img.qammunity.org/2022/formulas/mathematics/college/bsc245c74ctdn0ptf26etqnolsgp267hx4.png)
![y = 60 x](https://img.qammunity.org/2022/formulas/mathematics/college/27v2jdkn5dn6ilgov9g60frqtnc485j4k9.png)
