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.
A. 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 -5 to 100 in increments of 5. A ray extends from a plotted point. The coordinates of a plotted closed circle are (0, 2). An upward slanting arrow extends from the plotted point and passes through (6, 92).
B. 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 (2, 0). An upward slanting arrow extends from the plotted point and passes through (8 comma 90).
C. 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 (2, 0). An upward slanting arrow extends from the plotted point and passes through (8, 90).
D. 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).

Answer 1

D. It has the point (0,15) and goes to (30,75), which fits y = 15 + 2x (start at page 15 and increase 2 pages per minute).
