Dane Wolfe · Answer 1

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
