You can put this solution on YOUR website! ---
the relationship between your x data and you y data is not perfectly linear, but it is approximately linear
---
all you can do is approximate the linearity in your data with a linear regression
---
plug this (your x data, followed by your y data):
2 3 7 8 10 24 16 6.8 6 4.8
---
into this solver:

---
and click the "xxyy" button to properly sort your data, and get the slope and y-intercept of the regression line:
slope = -2.30434783
y-intercept = 25.346087
---
answer:
the slope-intercept form of the linear regression line that best fits your data:
y = -2.30434783x + 25.346087
