There is a proportional relationship between minutes and dollars per minute, shown on a graph of printing expenses. The graph passes through the point (1, 3.35). What is the slope of the graph? What is the unit rate? Complete the explanation.

The slope of the graph is 3.35. The unit rate is 3.35 dollars per minute. This means that for every 1 minute of printing, the cost is 3.35 dollars.

Did you know that the slope of a graph represents the rate of change between two variables? In the case of the graph of printing expenses, the slope represents the relationship between minutes and dollars per minute. By examining the graph, we can determine the unit rate, which is the amount of dollars spent per minute. To find the slope of the graph, we can use the formula: slope = (change in y) / (change in x). Given that the graph passes through the point (1, 3.35), we can start by considering this as our initial point. By comparing it to another point on the graph, we can calculate the change in y and the change in x. The resulting ratio will give us the slope of the graph. Additionally, the slope will also represent the unit rate, as it signifies the amount of dollars spent per minute. So, by determining the slope, we can uncover the unit rate of the graph of printing expenses.
