Given function f(x) which is described by "<span>Dawn writes 800 pages in 80 days".
From this function we can notice that Dawn writes 0 pages in 0 days, (i.e. the initial point of the function is point (0, 0).
Recall that the slope, m, of a line passing through points:
and 
is given by
Function f(x) passes through points (0, 0) and (80, 800).
Thus the slope of function f(x) is given by
Give function g(x), passing through points (2, -6) and (4, 12), the slope is given by
It can be seen that the slope of f(x) and the slope of g(x) are close.
