Answer:
Step-by-step explanation:
Remark
I'm not sure I know what you intend for the slope. I will take it as 12/3 = 4
If that is the case then what you have so far is
Solution
y = 4x + b
The given point determines b
<em>Givens</em>
x = 3
y = 2
<em>Given point</em>
2 = 4*3 + b
2 = 12 + b
b = 2 - 12
b = -10
The equation is y = 4x - 10

Answer:
C. The proof is done.
Step-by-step explanation:
i could be wrong but if i remember correctly QED stands for Quod Erat Demonstrandum
The derivative of 
at a point 
in the direction of a vector 
is
We have
and
Then the derivative at 
in the direction of 
is
