Final answer:
The slope of the revenue line on a graph represents the rate at which the website's revenue increases or decreases each day, and is calculated as the change in revenue over the change in time. The unit rate is the same as the slope, which would be the revenue change per day.
Step-by-step explanation:
When looking to find and interpret the slope of a website's revenue over several days depicted on a graph, we use the formula for slope, which is rise over run. Without specific coordinates from the graph, we'll need to select two clear points on the line and then calculate the difference in revenue (rise) and the difference in time (days or run).
Assuming we have two points on the line, the change in revenue divided by the change in time would give us the slope of the revenue line. The slope tells us the rate at which revenue is increasing or decreasing each day. If, for example, the slope was $50, this would mean that for each additional day, revenue increases by $50.
The unit rate in this context would refer to the revenue per day, which is actually the same as the slope of the revenue line. If the slope were $50 per day, the unit rate would be $50/day as well, indicating that they are indeed the same.
