Question

Willow is rereading her favorite book. She starts the day on page 15. Looking at the clock, she realizes that she can read 2 pages every minute. Choose the sketch of a graph that shows the relationship between the number of minutes Willow has been reading today and the page number she is on.(1 point)

A coordinate plane shows the x-axis, labeled as Number of Minutes, ranging from negative 2 to 30 in increments of 2, and the y-axis, labeled as Page Number, ranging from negative 5 to 100 in increments of 5. A ray extends from a plotted point. The coordinates of a plotted closed circle are left parenthesis 2 comma 0 right parenthesis. An upward slanting arrow extends from the plotted point and passes through left parenthesis 8 comma 90 right parenthesis.

Answer 1

To find the correct graph representing Willow's reading progress, we first need to determine how the page number changes over time.

Willow starts at page 15 and reads 2 pages per minute. The relationship can be described mathematically as:

\[ \text{Page number} = 15 + 2 \times (\text{number of minutes}) \]

1. At \( t = 0 \) minutes, she is on page 15:
\[ \text{Page number} = 15 + 2 \times 0 = 15 \]

2. At \( t = 1 \) minute, she is on page 17:
\[ \text{Page number} = 15 + 2 \times 1 = 17 \]

3. At \( t = 2 \) minutes, she is on page 19:
\[ \text{Page number} = 15 + 2 \times 2 = 19 \]

Continuing this pattern, we see that for every minute that passes, her page number increases by 2.

To summarize:
- Starting point: (0, 15)
- The slope of the graph is 2 (rise/run = 2/1).

Now, we can analyze the options given for the graph:

- The graph should start at the point (0, 15) on the y-axis.
- It must be a linear graph with a positive slope.

Among the options provided, the correct graph is:

**"A coordinate plane shows the x-axis, labeled as Number of Minutes, ranging from negative 2 to 30 in increments of 2, and the y-axis, labeled as Page Number, ranging from negative 5 to 100 in increments of 5. A ray extends from a plotted point. The coordinates of the plotted closed circle are (0, 15). An upward slanting arrow extends from the plotted point and passes through (30, 75)."**

This graph correctly reflects that Willow starts at page 15 and reads more pages over time.
