Context: Scatterplot with positive line of best fit, data from approximately $(0, 3)$ to $(8, 6.5)$.

Answer: Pick two points on the line: $(0, 3)$ and $(8, 6.5)$. $m = \frac{6.5 - 3}{8 - 0} = \frac{3.5}{8} \approx 0.44$

Why C: The slope $\approx 0.44$ matches the gentle upward trend. $\checkmark$

Traps:

• (A) $-2.27$ — negative and steep; data goes upward, not down.
• (B) $-0.44$ — right magnitude but wrong sign; line goes up.
• (D) $2.27$ — way too steep; would rise ~18 units over 8 x-units.
