**Reiny**, Wednesday, December 19, 2012 at 10:50pmlet's take some ordered pairs that fit the above description.

(25,3.5) , (35, 4.5), (45, 5.5), (15, 2.5 , (5, 1.5)

etc

in each case of pairs, the slope is 1/10 , and the function is linear.

so A = (1/10)m + b

using the given point (25,3.5)

3.5 = (1/10)(25) + b

b = 1

A = (1/10)m + 1
