Justin is running a 10-mile race. Data on the number of miles he has remaining in the race and how long he has been running is recorded in the table below. Create a line of best fit for the given data.

• y = -0.138x + 10.25

• y = -10.25x + 0.138

• y = 10.25x - 0.138

• y = 0.138x + 10.25

Michael is saving up money for a new car. Each month he saves as much money as he can. Data on the total amount of money he has saved over several months is listed in the table below.

• $875

• $925

• $900

• $850
