Final answer:
The given graph represents a linear relationship between the cost of game apps and the number of game apps purchased. The slope of the line is positive, indicating that as the number of game apps increases, the cost also increases.
Step-by-step explanation:
The given graph represents a linear relationship between the cost of game apps and the number of game apps purchased. To determine the slope of the line, we can use the formula: slope = (change in y)/(change in x).
From the graph, we can see that the cost of 2 game apps is $3.50, and the cost of 5 game apps is $8.75.
Substituting these values into the formula, we get slope = (8.75 - 3.50) / (5 - 2) = 5.25 / 3 = 1.75.
This means that for each additional game app, the cost increases by $1.75. Based on these calculations, the slope of the line is positive. Therefore, the true statements about the graph are:
- The slope of the line is positive.
- As the number of game apps increases, the cost also increases.
