7 = 3/4 (3) + c
28 = 9 + 4c
4c = - 19
c = - 19/4
y = 3/4x - 19/4
5 = 3/4x - 19/4
3/4x = 39/4
x = 13

Here we have the function

We want to find the following ratio:

Note that the limit of this for
is equivalent to the derivative of the function.
Here we have:

And

Therefore we have

And therefore,
