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.

changes in factors like average income and preferences can cause an entire demand curve to shift right or left. this causes a higher or lower quantity to be demanded at a given price. demand curves relate the prices and quantities demanded assuming no other factors change. it is important for consumers to know this information, because it is crucial for them to know what they can afford and can't afford. i hope this .
