Which of the following representation shows how one variable changes in response to another variable?

* models
*line graphs
*pie charts
*complex systems

I need to have a explanation and answer
thanks

where the answer?

thanks

The representation that shows how one variable changes in response to another variable is a line graph.

To understand how one variable changes in response to another variable, we use a line graph. A line graph is a type of chart that displays data points connected by line segments. The x-axis represents one variable, typically time or independent variable, and the y-axis represents the other variable or dependent variable. By plotting the respective values of the variables on the graph and connecting the data points, we can visually observe how the dependent variable changes in response to the independent variable.

So, the correct answer is: line graphs.
