Question

using the trendline on the graph, if you are 24 years old, how many emails per day would you expect to send?
about 25
about 72
about 35
about 12

Explanation:

Step1: Analyze the graph's axes

The x - axis (horizontal) represents age, and the y - axis (vertical) represents emails per day. We need to find the number of emails for a 24 - year - old.

Step2: Locate age 24 on the x - axis

Find the position corresponding to age 24 on the x - axis of the scatter plot with the trendline. Then, move vertically until we hit the trendline, and then horizontally to the y - axis to find the corresponding number of emails. From the trendline, when age is 24, the number of emails per day is about 35.

Answer:

about 35
