A) Find and interpret the C-intercept for the line (0, 30.52)

C(0) = 2.85n + 30.52 – 30.52 = C(0)- 30.52
C(0) = 30.52…
C-intercept is at $30.52 billion - 1990

B) Find and interpret the n-intercept for the line (-10.71)

C= 2.85n + 30.52 = 0 = 2.85n + 30.52… N = -30.52/2.85 = -10.71

C) Graph the line for n ranging from 0 through 20

please graph this equation

(0, 30.52) is not a line: it's a point.

There must be information that you have that we don't.
