Paul made flyers to promote the grand opening of his bookstore. He gave 20 flyers to his friends, and then handed out 9 flyers every hour. He decides to graph the number of flyers, y, given out over x hours. Which equation best describes Paul's graph?
Accepted Solution
A:
For this case, the first thing we must do is define variables. We have then: x: number of hours. y: number of flyers We now write the equation that represents this problem. We have then: y = 9x + 20 The slope of the graph m = 9 represents the number of flyers distributed every hour. The intersection with the axis and b = 20 represents the number of flyers that Paul distributed to his friends. Answer: An equation that best describes Paul's graph is: y = 9x + 20
