Make a system of points according to ordered pairs (z,c) and you have two known points (150,100) and (-10,0). Find the linear equation which contains these two points. You would want the result in slope-intercept form.
,
-
and find b,
; using either of the two known points.
A different example, but the same basic idea shown here:
