Answer:
![F = 1.8C + 32](https://tex.z-dn.net/?f=F%20%3D%201.8C%20%2B%2032)
Step-by-step explanation:
Given
The attached table
Required
The relationship between both temperatures
<em>This implies that we calculate the table equation</em>
First, we calculate the slope (m)
![m = \frac{F_2 - F_1}{C_2 - C_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7BF_2%20-%20F_1%7D%7BC_2%20-%20C_1%7D)
Where:
![(C_1,F_1) = (0,32)](https://tex.z-dn.net/?f=%28C_1%2CF_1%29%20%3D%20%280%2C32%29)
![(C_2,F_2) = (20,68)](https://tex.z-dn.net/?f=%28C_2%2CF_2%29%20%3D%20%2820%2C68%29)
So, we have:
![m = \frac{68 - 32}{20 - 0}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B68%20-%2032%7D%7B20%20-%200%7D)
![m = \frac{36}{20}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B36%7D%7B20%7D)
![m = 1.8](https://tex.z-dn.net/?f=m%20%3D%201.8)
The equation is then calculated using:
![F = m(C - C_1) + F_1](https://tex.z-dn.net/?f=F%20%3D%20m%28C%20-%20C_1%29%20%2B%20F_1)
This gives:
![F = 1.8(C - 0) + 32](https://tex.z-dn.net/?f=F%20%3D%201.8%28C%20-%200%29%20%2B%2032)
![F = 1.8(C ) + 32](https://tex.z-dn.net/?f=F%20%3D%201.8%28C%20%29%20%2B%2032)
![F = 1.8C + 32](https://tex.z-dn.net/?f=F%20%3D%201.8C%20%2B%2032)
