Find Epsilon in Beer's Law Equation for Absorbance vs. Concentration Graph

[Hikari]

Homework Statement

I am given a linear graph that is Absorbance vs. Concentration. How do I find epsilon in the beer's law equation?

Homework Equations

Beer's law: A = Epsilon x L x c

The Attempt at a Solution

I just need a general explanation. Thanks.

Absorbance vs. Concentration

A = Epsilon x L x c

Gee. Let me think. What do those symbols and letters mean/stand for?

Hint:
A = εbc ⇔ y = mx + b

Hint 2: Because the b term (y-intercept) throws many off. What would the absorbance be if C = 0?
