Question

In Lena’s job of making home deliveries of groceries for a supermarket, the graph shows her distance from the store on her first trip for the day. What are the variables in this scenario, and how are the variables related at various points on the graph?

Please describe the variables and explain how they are related at different points on the graph.

Answer 1

The variables in this scenario are distance from the store (dependent variable) and time (independent variable). The distance from the store changes as Lena makes her deliveries, and this relationship is represented on the graph.

Step-by-step explanation:

The variables in this scenario are distance from the store (dependent variable) and time (independent variable). The distance from the store is represented on the y-axis of the graph, while time is represented on the x-axis. As Lena makes her deliveries, the distance from the store changes depending on the time. At different points on the graph, the variables are related as follows:

• At the start of Lena's trip (time = 0), the distance from the store is also 0. This is represented by the point (0,0) on the graph.
• As time increases, Lena gets farther from the store, so the distance on the y-axis also increases. This is shown by the upward-sloping line on the graph.
• At the end of Lena's trip, the distance from the store is at its maximum, which is represented by the point on the graph where the line levels off.
