Apologies for the incorrect response. Let's re-evaluate the table to determine the correct answers:
x - tickets: 4 9 8 5 7
y - $ earned: 48 108 96 60 84
a. Every ticket sold is 12 dollars earned. This can be found by dividing the money earned (y) by the number of tickets sold (x). For example, in the first row, 48/4 = 12, and it holds true for all other rows as well.
b. Dollars/1 ticket is called the "average ticket price" or "revenue per ticket."
c. This relationship is not linear because the ratio of money earned to tickets sold (y/x) is not constant. For example, in the second row, 108/9 equals 12, but in the third row, 96/8 equals 12 as well, indicating a linear relationship. However, the other rows do not follow this pattern, so the relationship is not linear.
Apologies for the confusion in the previous response.
