Question

Match each description with the correct graph. Not all graphs will be used.

Prompt 1 My graph is non-proportional with a negative y-intercept.
Prompt 2 My graph is proportional with a negative slope.
Prompt 3 My graph is non-proportional with a positive slope.

Answer 1

1. C

2. B

3. A

Explanation:

Answer 2

The matches are D for "non-proportional with a negative y-intercept," B for "proportional with a negative slope," and A for "non-proportional with a positive slope."

To match each description with the correct graph:

1. Graph with a negative y-intercept and non-proportional: This corresponds to a line that crosses the y-axis below the origin. The correct graph is likely to be one with a negative y-intercept and a non-proportional relationship. (D)

2. Graph with a negative slope and proportional: This corresponds to a line with a negative slope that passes through the origin. The correct graph is likely to be one with a proportional relationship and a negative slope. (B)

3. Graph with a positive slope and non-proportional: This corresponds to a line with a positive slope that does not pass through the origin. The correct graph is likely to be one with a non-proportional relationship and a positive slope. (A)
