Plan A:
15+(0.25x)
15+(0.25×80)
15+(20)
35
Plan B:
20+(0.05x)
20+(0.05×300)
20+(15)
35
I am sure there are other numbers that you can use but I just choose the number 35! Good luck!
Answer: The derivative of the function
is
.
Step-by-step explanation:
We know that the derivative of
with respect to x is given by :
(1)
The given function is 
Differential both sides with respect to x , we get

( Using (1))
Therefore , the derivative of the function
is
.
To answer this (specifically the first one) you have to count how many spaces each point moves. (How many spaces up/down does it go? Left/right?) then you put rise (up/down) over run (left/right) and you should get the slope!
