Which of the following representations shows how one variable changes in response to another variable. a. models b. line graphs c. pie charts d. complex system

Answer is (B) Line Graphs.

How X varies with Y, and what functional form it takes can be studied using a simple line graph.

Rationale:

Models are created to study the variables that are dependent on the independent variables. It is not a visual representation of relationship between the two dependent variables.

Pie charts are created to show the distribution of quantities in percentages. It does not highlight a relationship between two dependent variables.

Complex systems are used to model the systemic changes in a real-world scenario. It is not used to give a visual representation of the relationship between two dependent variables.

do yall know the answer?

the correct answer is b
