More skills with logarithms, AND with linear equations.

x, time in minutes
N, initial population
y, resulting population
k, a constant

------THIS is now a linear equation with slope k, and vertical axis intercept . You need to use your vertical axis coordinates as . Your two data points are (x, ln(y)).
