Theoretical y intercept based on beer's law
Webb1 nov. 2012 · The equation of a straight line is usually taught in the form: y = mx + c which succinctly expresses the fact that if we plot y against x and the variables obey a relationship of this form we will obtain a straight line graph with gradient or slope m and intercept (where the line crosses the y-axis) c ( fig 1 ) Webb7 dec. 2015 · The Mathematics of Beer’s Law – Concentration tabBeer’s law is a linear relationship between absorbance (A) and three independent variables:the molar absorptivity (a), the pathlength (b), and the concentration (c). The law takesthe form of y = mx + b, where m is the slope and b is the y-intercept.
