1. **State the problem:** We need to determine which number line correctly displays the points $[-0.9, -2 \frac{1}{2}, 0.25, -\frac{3}{4}]$. 2. **Convert all points to decimal form for easy comparison:** - $-0.9$ is already decimal. - $-2 \frac{1}{2} = -2.5$. - $0.25$ is already decimal. - $-\frac{3}{4} = -0.75$. 3. **Order the points from smallest to largest:** $$-2.5 < -0.9 < -0.75 < 0.25$$ 4. **Check each option's order:** - A) $-2.5, -0.9, -0.75, 0.25$ matches the correct order. - B) $-2.5, -0.75, 0.25, 0.9$ is incorrect because $-0.9$ is missing and $-0.75$ comes before $-0.9$. - C) $-2.5, 0.25, 0.75, 0.9$ is incorrect because $-0.9$ and $-0.75$ are missing and order is wrong. - D) $-0.25, 0.75, 0.9, 2.5$ is incorrect because points are different and range is different. 5. **Conclusion:** Option A correctly displays the points in order on the number line. **Final answer:** Option A
