Nate went on a trip, and he used a table of values to repeatedly record the time he had been traveling and the distance from his starting point. The function represented by the table of values is linear, and the rate of change is 50 miles per hour. What is one way for Nate to determine the initial value?

The initial value is the distance from the starting point when Nate has traveled for 0 hours. Since distance increases by 50 miles for each additional hour, Nate can work backward through the table by subtracting 50 miles for each hour to find that starting value. This matches “By repeatedly subtracting 50.”
