Part A: The number line

1. Start at 0. Turn on Fraction mode, set the numerator to 1 and the denominator to 2, then press Add once. What is the value now? 1 pt
Answer:
2. From that value (0.5), press Add one more time. Where does the point land? 1 pt
  • 0.5
  • 1
  • 1.5
  • 2
3. Set the fraction to 3/4. Press Reset, then press Subtract once. What is the value? 1 pt
Answer:
4. Drag the point so it sits at 3/4. What number is its opposite? 1 pt
  • −3/4
  • 3/4
  • 4/3
  • −4/3
5. Which number is greater, −2 or −5? 1 pt
  • −2
  • −5
  • They are equal
  • You cannot tell
6. What is the absolute value of −5? 1 pt
Answer:
7. Switch to decimal mode. Set the decimal to 2.5. Start at −4 and press Add. What is the value? 1 pt
Answer:

Part B: The coordinate plane

8. Switch to Plane mode and enter x = 3, y = −2. Which quadrant is the point in? 1 pt
  • Quadrant I
  • Quadrant II
  • Quadrant III
  • Quadrant IV
9. Enter x = −4, y = 5. Which quadrant is the point in? 1 pt
  • Quadrant I
  • Quadrant II
  • Quadrant III
  • Quadrant IV
10. Enter x = −6, y = 2. The module shows |x|. What is |x|? 1 pt
Answer:
11. What is the distance between the points (2, 3) and (7, 3)? 1 pt
Answer:
12. Reflect the point (3, −2) across the x-axis. Which point do you get? 1 pt
  • (3, 2)
  • (−3, −2)
  • (−3, 2)
  • (2, 3)
13. Describe how the signs of the coordinates tell you which quadrant a point is in. Give one example. 2 pts
