Question 178784: How to solve C= 2.85n + 30.52 to a) Find and interpret the C-intercept for the line?
b) Find and interpret the n-intercept for the line?
c) Graph the line for n ranging from 0 through 20?
Can you please offer me some helpful information on how to solve equations such as these?
Thank you,

Answer by Mathtut(3670) (Show Source): You can put this solution on YOUR website!
a) it would correctly be the C intercept not the n intercept
:
remember the slope intercept equation y=mx+b......where m is the slope and b is
the y intercept. This is the same thing only its C instead of y.
:
so the C-intercept is 30.52. We cannot really interpret it without more information which you probably didnt give us. If you want it interpreted email me the rest of the problem.
:
for n=0 to 20
you just plug the values in for n and solve for C
:
example: n=0, C=30.52...so (0,30.52)
:
n=1, C=2.85(1)+30.52=33.37...so (1,33.37)
:
you'll find for every increase in n by 1 that the C will increase by 2.85
:
so n=2 is 33.37+2.85=36.22
...n=3 is 36.22+2.85
:
and so it continues to 20
:
here is the graph:
