Use the points (5,150) and (10,200)
slope = (200-150)/(10-5) = 50/5 = 10
------------------------
intercept: 150 = 10(5) + b
b = 100
---
Equation:
Pay = 10x + 100 where x is # of subscriptions Sheryl sells.
------------------------------
(b) What is her weekly pay if she sells 40 subscriptions?
p(40) = 10*40 + 100 = $500
