I made a graph with solutions 1 - 5 and got the slope value of it, how do I use this value to find the concentrations of the rest of my solutions? (6 7 and I also have the absorbance values for solutions 6 7 and 8. How can I link these together?

Question asks "Use the equation for the best-fit line (I assume that's the slope right?) and absorbance values to calculate the equilibrium concentration of complex in solutions 6 7 8.
