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
