Question

credits needed to graduate
the input, or dependent variable, is courses completed.
the output, or dependent variable, is credits needed to graduate.
the input, or independent variable, is credits needed to graduate.
the output, or independent variable, is courses completed.

Explanation:

In a scatter plot, the x-axis represents the independent (input) variable, and the y-axis represents the dependent (output) variable, as the value on the y-axis depends on the x-axis value. Here, x is "Courses Completed" (independent/input), y is "Credits Needed to Graduate" (dependent/output). We match this to the correct option.

Answer:

The output, or dependent variable, is credits needed to graduate.
