A sample of the unknown complex is analyzed and has an absorbance of 0.528. What is the molar concentration of Cu^2+ ions in the unknown solution?

Additional details:

y=2.2617x - 0.0535

R^2=0.994

Epsilon=2.26

Absorbance is the Y-axis, M is on the X-axis

Everytime I put it in as
\(c=\frac{A}{\epsilon (b)}\)

I get 0.234, and it informs me that I have assumed the Y intercept is zero, and as it is not zero in the equation for best fit line, I should use the full equation of the line.
