Julia created a scatter plot to show the relationship between the number of fans at a school volleyball game, x , and the amount of money in dollars raised by selling concessions, y . She then drew the trend line and calculated the equation to be y=5.2x−20 . Select the correct button in the table to show whether each statement is true or false.

True: Slope is 5.2, y-intercept is -20. Each additional fan increases money by $5.2. With zero fans, -$20 expected.

It seems there might be a table or buttons missing in your question. However, based on the information provided, I can make statements about the relationship between the number of fans at a school volleyball game (x) and the amount of money raised by selling concessions (y) with the given trend line equation y = 5.2x - 20.

1. Statement: The slope of the trend line is 5.2.

True. The coefficient of x in the equation represents the slope of the line, and in this case, it is 5.2.

2. Statement: The y-intercept of the trend line is -20.

True. The constant term in the equation, -20, represents the y-intercept where the line crosses the y-axis.

3. Statement: For every additional fan, the amount of money raised increases by $5.2.

True. The slope of the line (5.2) indicates the rate of change, meaning for each additional fan (increase in x by 1), the amount of money raised (y) increases by $5.2.

4. Statement: If there are zero fans, the expected amount of money raised is -$20.

True. When x (number of fans) is zero, the y-intercept (-20) represents the expected amount of money raised.

In summary, based on the provided information and the given trend line equation, the statements are all true. If you have a specific table or buttons that need to be addressed, please provide more details, and I'll be happy to assist further.
