Which of the following representaions shows how one variable changes in response to another variable a. models b. line graphs c. pine charts d. complex systems

The correct answer would be option B, Line Graphs.

Explanation:

Line Graphs show how one variable changes in response to another variable.

Line graphs are graphs in which points are plotted and those points are joined together to form a pattern which shows how one variable changes with the change in other variable.

Usually two variables are plotted, and we can see them changing with the change in one variable. For example if demand and supply are to be plotted on the graph, then through this line graph we can see how supply changes when demand changes and vice versa.
