Your answer is 0, because the equation for this is y=1. Only vertical lines can have an undefined slope because the x value never changes. Hope this helps.

Lololololol. I long since forgot how to do this. rip
Given the equation:

since both bases are 6, we can equate both exponents to get the following equation:

solving for x, we get:

therefore, the solution of the equation is x = 4
So because you will have $2 no matter how many cups you sell the equation starts off as AA = 2
Next, you add the dependent variable, because 1 cup of cc = $0.50 you add 0.5cc to the equation (it can also be written as 1/2cc), to complete the equation.
AA = 1/2cc +2
