Question

Jamie rode her bike home for 5 blocks before realizing she forgot her math book at school and would need it for her homework. She rode back to school, found her math book, and then rode home.

Which graph best represents the scenario described?

A coordinate plane graph is shown. The axis is labeled time and the y-axis is labeled distance from home in blocks. A line begins at 0 comma 0, increases to 5 comma 5, decreases to 8 comma 0 and stays horizontal to 12 comma 0. The line increases to 16 comma 9.
A coordinate plane graph is shown. The x-axis is labeled time and the y-axis is labeled distance from home in blocks. A line begins at 0 comma 9, decreases to 5 comma 4, increases to 9 comma 9 and stays horizontal to 13 comma 9. The line decreases to 17 comma 0.
A coordinate plane graph is shown. The axis is labeled time and the y-axis is labeled distance from home in blocks. A line begins at 0 comma 8, decreases to 5 comma 5, decreases again to 8 comma 3, then stays horizontal to 12 comma 3. The line decreases to 17 comma 0.

Answer 1

B)

Explanation:

The y axis is distance from home, so she can't start at (0,0), because that would imply that Jamie started at home. Thus, it has to be B or C. However, C never includes a section of the graph increasing, which is necessary to represent Jamie going further from home (back to school to get her book) before returning home, at y=0. Therefore, the answer has to be B)
