Question 23 • 2025-2026_MDCPS_1205070-M/J Grade 8 Pre-Algebra Sem 1-CR
There are 60 minutes in an hour. The total number of minutes is a function of the number of hours, as shown in the table. Does this situation represent a linear or non-linear function, and why?Hours vs. MinutesHoursMinutes1602120318042405300
Answer
A
It represents a linear function because there is a constant rate of change.
B
It represents a linear function because there is not a constant rate of change.
C
It represents a non-linear function because there is a constant rate of change.
D
It represents a non-linear function because there is not a constant rate of change.
Explanation
Each additional hour adds 60 minutes: the minutes go from 60 to 120 to 180 to 240 to 300, increasing by 60 each time. A function with a constant rate of change is linear. Therefore, choice A is correct: it represents a linear function because there is a constant rate of change.
