Answer: B. Negative
Step-by-step explanation:
- A. Zero - a line with a slope of zero is horizontal ❌
- B. Negative - a line with a negative slope is highest to the left and lowest to the right. This is because when x increases, the y decreases, and when x decreases, y increases (the two variables are negatively related)✅
- C. Positive - a line with a positive slope is highest to the right and lowest to the left. This is because when x increases, the y increase, and when x decreases, y decreases (the two variables are positively related)❌
- D Undefined - a line with an undefined slope is vertical ❌
If you look at the graph, you will realize that it is highest to the left and lowest to the right and that as x increases, the y decreases, and when x decreases, y increases. Thus it has a NEGATIVE slope.
