Jaxon practices the piano the same number of minutes each day. The relationship between the number of days, x, and the total number of minutes he practices, y, is represented by the graph below.
Two points, C and A, are labeled. Which statement about the graph is true?
0
Number of Days
Total Practice Time (in minutes)
x
y
0
Number of Days
Total Practice Time (in minutes)
C
A
Point A means that the unit rate is 30 minutes per day
Point A means that the unit rate is 30 days per minute
Point C means that the unit rate is 3 days per minute
Point C means that the unit rate is 90 minutes per day
The correct statement about the graph is:
Point C means that the unit rate is 3 days per minute
Point A means that the unit rate is 30 minutes per day.
To determine which statement about the graph is true, we need to examine the coordinates of points A and C.
Looking at point A, we can see that it has coordinates (0, 30). This means that when the number of days (x) is 0, the total practice time (y) is 30 minutes.
Based on this information, we can conclude that the statement "Point A means that the unit rate is 30 minutes per day" is true.
