You can put this solution on YOUR website! If a project takes 2.5 resources 71 weeks to complete and 3.5 resources 46 weeks to complete, how many weeks will it take 5.5 resources?
---
You have 2 points (2.5,71) and (3.5,46)
slope = (46-71)/1 = -25
----
Form:: y = mx + b
Solve for "b":
46 = -2*3.5 = b
b = 39
----
Equation:
y = -2x + 39
-----
Ans: f(5.5) = -2*5.5+39 = -11+39 = 28
