Final answer:

The slope of the demand curve is 40.

Step-by-step explanation:

The demand curve for pizza can be determined by calculating the slope using the formula:

Slope = (Change in Quantity Demanded) / (Change in Price)

Using the given information, we can calculate the change in quantity demanded and change in price:

Change in Quantity Demanded = 300 - 100 = 200 slices

Change in Price = $5 - $10 = -$5

Therefore, the slope of the demand curve is: -200 / -5 = 40

So, the correct answer is option (b) 40.
