Question

1. which of these scatter plots has a good line of best fit? a. scatter plot, b. scatter plot, c. scatter plot, d. scatter plot

Explanation:

Step1: Recall Line of Best Fit Criterion

A good line of best fit should have data points closely clustered around it, showing a strong linear trend (either positive or negative correlation).

Step2: Analyze Each Option

• Option A: Points are somewhat spread; not all close to the line.
• Option B: Points are more scattered, especially at higher x - values.
• Option C: Most data points lie very close to the line, showing a clear negative linear trend.
• Option D: Points at higher x - values (around x = 9) are above the line, less clustered than in Option C.

Answer:

C
