Question

the scatter plot shows one athletes time spent exercising in minutes and the number of calories burned during that time.

define the independent and dependent variables.

• the independent variable is the calories burned, and the dependent variable is the minutes spent exercising.
• the independent variable is the hours spent exercising, and the dependent variable is the calories added.
• the independent variable is the calories added, and the dependent variable is the hours spent exercising.
• the independent variable is the minutes spent exercising, and the dependent variable is the calories burned.

<reasoning>

Identify the horizontal axis variable

Using the Scatter Plots knowledge point
The horizontal axis (\(x\)-axis) represents the independent variable, which is labeled "Exercise Time (in minutes)".

Identify the vertical axis variable

Using the Scatter Plots knowledge point
The vertical axis (\(y\)-axis) represents the dependent variable, which is labeled "Calories Burned".

Match with the correct option

The independent variable is the minutes spent exercising, and the dependent variable is the calories burned.
