copy and paste the above x,y pair list in to this solver:

---
equation of the best fitting line:
y = -5x + 70
---
correlation coefficient = -1
---
the absolute value of correlation coefficient = 1 so the data is perfectly linear.
the closer to zero the absolute value of the correlation coefficient, the less linear is the data
---
the sign of correlation coefficient is negative. this means the regression line has a negative slope (is decreasing)
---
answer:
the data's relationship is a decreasing linear function
