Answer 2

Scatter plots are used to represent data of dual numerical values.

The true statements about the scatter plot of Hana's purchase are:

• The slope approximates the average cost of one book.
• The y-intercept approximates the cost of Hana's lunch.

I've added as an attachment, the scatter plot that represents Hana's purchase.

From the attached plot, we have the following observations

• The x-axis represents the number of books
• The y-axis represents the amount spent

Because the x-values represents the number of books, the slope of the graph would represent the cost of a book.

The amount spent on a meal is constant;

This amount can be gotten when the number of books is 0;

In other words, the y-intercept represents the cost of Hana's meal.

Hence, the true statements are: (c) and (d)
