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:

Step1: Recall Variable Definitions

In a graph, the independent variable (input) is on the x - axis, and the dependent variable (output) is on the y - axis. Here, x - axis is "Courses Completed", y - axis is "Credits Needed to Graduate".

Step2: Analyze Each Option

• Option 1: Dependent variable is not input (input is independent). So wrong.
• Option 2: Output (dependent) is y - axis (Credits Needed to Graduate). Correct.
• Option 3: Input (independent) is x - axis (Courses Completed), not y - axis. Wrong.
• Option 4: Output is dependent, not independent. And independent variable is x - axis (Courses Completed) but it's input, not output. Wrong.

Answer:

B. The output, or dependent variable, is credits needed to graduate. (Assuming the options are labeled as A, B, C, D with this option as B)
