Final answer:
The slope represents the production rate of snowballs per hour, which is 26. Therefore, the correct answer to the question is 26, option b.
Step-by-step explanation:
In this mathematics problem, we are asked to determine the slope of the scenario where snowballs are produced over time. The slope is the rate of change in the number of snowballs made per hour. Since the scenario states that snowballs are being created at a rate of 26 per hour, the slope is 26. The initial number of snowballs does not affect the slope; it is the initial value or the y-intercept in a linear equation.
