If you were to plot the coulomb’s law formula on a graph , where the slope is equal to kq1q2. Y axis is F and x-axis is 1/r. The equation for the graph is a linear equation where m=slope and b=intercept. What is the meaning/value of this intercept. Example Graph : F vs 1/r y= mx + b y=(k*2.6x10^-9)x + 2.3x10^-6 Where m=kq1q2 , what would b represent ?

How can we use the y-intercept and the slope from the graph to
determine Planck's Constant and the work function in the equation
KEmax=hf−ϕ ?
(Note: I know the linearization is showing the y-int. and slope to
be zero because the values are so small, but conceptually how could
we do it?)
