You can put this solution on YOUR website! data:
1990 1995 1998 1999 2000 30 36 37 42 49
---
the data is not linear, but is approximately linear, so you can use linear regression to obtain an equation that models the data
---
plug this:
1990 1995 1998 1999 2000 30 36 37 42 49
into this regression solver:

Result:
slope = 1.57055215
y-intercept = -3096.65031
---
Answer:
the linear equation model is:
y = 1.57055215x - 3096.65031
