Given

Solving (a): The cost function:
From the given parameter, it shows that the number of floor has no effect on the floors.
So, represent the floors with x.
The cost function is:

Solving (b): The slope and its interpretation
A function is represented as:

Where:

By comparing:
to 

So:

<em>What it means is that, no matter the number of floors, the cost remains unchanged.</em>
