When Jules loses a golf ball he takes another from the box. Which graph models this relationship?

Answer

A

Image with description On a coordinate plane, the x-axis is labeled golf balls lost and ranges from 0 to 10 in increments of 1. The y-axis is labeled golf balls in box and ranges from 0 to 10 in increments of 1. A segment begins at (0 comma 10) and extends to (10 comma 0).

B

Image with description On a coordinate plane, the x-axis is labeled golf balls lost and ranges from 0 to 10 in increments of 1. The y-axis is labeled golf balls in box and ranges from 0 to 10 in increments of 1. A point is at (0 comma 10). A point is at (1 comma 9). A point is at (2 comma 8). A point is at (3 comma 7). A point is at (4 comma 6). A point is at (5 comma 5). A point is at (6 comma 4). A point is at (7 comma 3). A point is at (8 comma 2). A point is at (9 comma 1). A point is at (10 comma 0).

C

Image with description On a coordinate plane, the x-axis is labeled golf balls lost and ranges from 0 to 10 in increments of 1. The y-axis is labeled golf balls in box and ranges from 0 to 10 in increments of 1. A segment begins at (0 comma 0) and extends to (10 comma 10).

D

Image with description On a coordinate plane, the x-axis is labeled golf balls lost and ranges from 0 to 10 in increments of 1. The y-axis is labeled golf balls in box and ranges from 0 to 10 in increments of 1. A point is at (0 comma 0). A point is at (1 comma 1). A point is at (2 comma 2). A point is at (3 comma 3). A point is at (4 comma 4). A point is at (5 comma 5). A point is at (6 comma 6). A point is at (7 comma 7). A point is at (8 comma 8). A point is at (9 comma 9). A point is at (10 comma 10).

Explanation

The number of golf balls in the box starts at 10 and decreases by 1 for each ball lost, so the relationship is y = 10 − x. Since golf balls are counted in whole numbers, the graph should show separate points such as (0, 10), (1, 9), and (2, 8), rather than a continuous segment. Choice B shows those points.
