Line & Curve of Best Fit

The table shows the height and shoe sizes of several students. Use the line of best fit to predict a student's height if they wear a size 7 shoe.

The table shows how much money Jon has in his bank account each year. Use the equation of best fit to estimate how much was in his account 18 years after he opened it.

Caroline weighs her new puppy every month to see how much it has grown. Use the equation of best fit to predict how much her puppy will weigh after 1 year.

A scientist dropped an object from a height of 200 feet. She recorded the height of the object in 0.5-second intervals. Her data is shown. Based on the quadratic model, which best approximates the height at 3 seconds?

Using the quadratic curve of best fit, which equation most closely represents the set of data?

This table shows the number of months used and the approximate distances driven, in miles, for six buses in a school district. Using the line of best fit for these data, which value is the best prediction of the distance, in miles, by a bus that has been used for 40 months?
