Question

The profit at a factory that makes CD's can be computed using the linear equation p = 2.5d - 1000 where p is the profit and d is the number of CD's sold. What is the slope and what does it represent?

Answer 1

The slope is 2.5/1 such that 2.5 rise and 1 is run.

It represents the number of CD's.

Answer 2

This slope represents the profit increase by the sales of one CD.

Explanation:

The profit at a factory that makes CD's can be computed using the linear equation P = 2.5d + 1000

Where P is profit and d is the number of CD's sold.

In this liner function 2.5 represents the slope.

This slope represents the profit increase by the sales of one CD.
