### Some graphing and various equation problems

1.) The national cost "C" in billions of dollars for dental services can be modeled by the linear equation: C = 2.85n+ 30.52 where n is the number of years since 1990 (Health Care Financing Administration, www.hcfa.gov). a) Find and interpret the C-intercept for the line. Put n = 0, we will get C = 30.52 C-interc
