Question 298980
Each hour, a wood-harvesting machine cuts the same number of logs and places them on a pile. 
At 8 am, there are 13 logs on the pile. 
At 11 am, the pile has grown to 46 logs. 
How many logs will the pile contain at 6 pm?
----
You have two points: (0,13), where 0 represents 8am,
and (3,46), where 3 represents 11am.
----
Equation ?
slope = (46-13)/(3-0) = 11
intercept = 13
----------------------
f(x) = 11x + 13 where x is the # of hours after 8am
----
How many logs will the pile contain at 6 pm?
At 6pm, x = 10
f(10) = 11*10 + 13
f(10) = 126 (# of logs at 6pm)
