Question

lila has a new watch that tracks her heart rate. she notices that her heart rate goes up and down often, but that gym class makes it rise the most. on fridays, lila has gym class early in the morning. which graph could show lila’s heart rate during school on friday?

Explanation:

Step1: Analyze the context

Lila has gym class early on Friday, so her heart rate should rise early (low x - value, high y - value) and then maybe fluctuate. The first graph has the heart rate activity starting at a lower x (earlier time) compared to the second.

Step2: Compare the two graphs

The first graph's heart rate pattern starts earlier (closer to the start of the x - axis) which matches the early gym class. The second graph's pattern starts later. So the first graph (top one) is the correct one as it shows the heart rate rising early (due to gym) and then other fluctuations.

Answer:

The top graph (the first one with the heart rate curve starting at a lower x - value) shows Lila's heart rate during school on Friday.
