Question

You develop an app to help students complete their homework. To earn money, you sell advertising space on the app’s main screen. An advertiser pays you $15 per month and an additional $0.004 each time the app is opened. Graph the linear equation that represents the monthly income y (in dollars) when the app is opened x times.

Answer 1

15 + 0.004
`*` x = y

Explanation:

Answer 2

Let y be the monthly income and x be the number of times the app is opened.

Then the required linear equation will be To find the coordinates, substitute x=0 in the equation, we get

The first coordinate of above linear equation is (0,25).Substitute x=100 in the equation, we get

The second coordinate of above equation is (100,25.3).(we can substitute x as per our choice )With the use of these coordinates (0,25) and (100,25.3), we plot the below graph.
