Final answer:
The question involves creating an equation to show the linear relationship between the number of downloads of a song and income, and plotting the points. We use the equation i=2d to find the income for each given number of downloads and then plot these points on a graph.
Step-by-step explanation:
The subject of this question is to find the relationship between the number of downloads and the resulting income, which can be interpreted as linear. We are provided with some data points indicating the number of downloads and the income, but there seems to be an error in the table. However, we can create an equation to represent the situation, given as i = 2d, where i is the income and d is the number of downloads. If a song is priced at $2 per download, for every additional download, the income increases linearly by $2.
To correct the given information and plot the points, we need to calculate income using the provided downloads and the equation given, for example:
- If d = 7, then i = 2(7) = $14
- If d = 10, then i = 2(10) = $20
- If d = 22, then i = 2(22) = $44
- If d = 35, then i = 2(35) = $70
To graph these points, we would plot them on a coordinate system with downloads on the horizontal axis and income on the vertical axis.
