The equation of the line of best fit is an illustration of a linear function

The teenager would spend $9 on food if he or she is at the mall for three hours.

How to determine the amount spent on food?

The equation of the line of best fit is given as:

y = 2x + 3

When the teenager spends 3 hours in the mall, it means that:

x = 3

So, we have:

y = 2 * 3 + 3

Evaluate the product

y = 6 + 3

Evaluate the sum

y = 9

Hence, the teenager would spend $9 on food if he or she is at the mall for three hours.
