Answer 1

We need to read the graph to see which are the two quantities related and how these are related.

The two quantities on the graph are:

• Distance from Elena's house
• Time.

Such that the distance from Elena's house is a function of the time.

How to read the graph?

We need to only read graph A, notice that she is coming back from school and going home, the graph starts at a high value and ends at zero. So we can assume that the vertical zero represents her home.

We know two events, first, she goes home and needs to come back to search for something, this is represented with the first "inverted peak" of graph A, then we have a constant line, that represents the time she is in the school looking something in her locker.

Then she goes home again, this time she finds a friend and goes to the library (this is why the line goes up again) and then she stops at the library for some time (this is why the line is horizontal for some time). Finally, she goes home, represented by the last segment of the line that intercepts the horizontal axis.

Then the two things represented in the graph are:

Distance from Elena's house (in the vertical axis) and time (in the horizontal axis).

This means that the distance from Elena's house is a function of time.

(The quantity in the vertical axis is a function of the quantity in the horizontal axis).
