PLEASE HELP!
The total healthcare expenditures E (in billions of dollars) in the United States from 1990 to 2001 are below.

Year-1990,1991,1992,1993,1994,1995
Expenditures, E-696, 762, 827, 888, 937, 990

Year- 1996, 1997, 1998, 1999, 2000, 2001
Expenditures, E- 1039, 1093, 1150, 1220, 1310, 1425

A) Use graphing utility to create a scatter plot for these data. Let t represent the year, with t=0 corresponding to 1990. Do the data appear linear?
I was able to input the information into my calculator but do I need to come up with an equation to put in there as well?
