Maria got a fitness tracker for her birthday, and she started using it a few days later. she's

been tracking how many days have passed, x, and how many steps she's taken in total, y.

based on the data, she calculated the line of best fit.

the equation for the line of best fit is y = 5,000x - 1,000.

use the equation for the line of best fit to predict the total number of days it will take for

maria to reach 99,000 steps.
