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?
Answer
A
By repeatedly subtracting 50.
B
By repeatedly dividing by 50.
C
By repeatedly adding 50.
D
By repeatedly multiplying by 50.
Explanation
A rate of change of 50 miles per hour means the distance increases by 50 miles for each hour traveled. To find the initial value, work backward from a recorded distance toward time zero, subtracting 50 miles for each hour step. So Nate can determine it by repeatedly subtracting 50.
