You can put this solution on YOUR website!
x: 2 / 4 / 6 / 8 / 10
y: 6.2/ 22.5/ 40.2/ 55.4 / 72.1
---
put the data into x,y pair list format:
2 6.2 4 22.5 6 40.2 8 55.4 10 72.1
---
copy and paste the above x,y pair list in to this solver:

---
equation of the best fitting line:
y = 8.235x - 10.13
---
value of y for x = 5 ...
y = 8.235x - 10.13
y = 8.235*5 - 10.13
y = 31.045
