The slope gives information of how the number of messages sent changes as the age increases, and the y-intercept is not feasible.
What does the slope mean?
We can see that the line has a negative slope, in the given experiment, the slope would say how the number of text messages sent per day changes.
So, as the age increases, the number of text messages sent per day decreases.
What does the y-intercept mean?
The y-intercept would give information about the number of text messages that someone with 0 years sends per day, obviously, this is not feasible.
Finally, if we add the point (40, 0), the slope would decrease a little bit. (take in mind that (40, 0) would be an outlier from the given set).
