Part 2: Subjective - Plotting & Analyzing

Follow the instructions for each question. You will need to draw on the grid above to find the answers.

• 11. Plot the following points on the grid and label them: J(3, 9), K(-6, -7), and L(8, 2). In which Quadrant is point K located?
  Answer:
• 12. Plot the points M(1, 1), N(1, 5), P(5, 5), and Q(5, 1). Connect the points in order from M → N → P → Q → M. What shape did you draw?
  Answer:
• 13. Start at point B (-5, 6) on the grid. Move 4 units to the right and 8 units down. What are the coordinates of your new location?
  Answer: (, )
• 14. A rectangle has three corners at (-7, 1), (3, 1), and (3, -5). Plot these points. What are the coordinates of the fourth corner needed to complete the rectangle?
  Answer: (, )
• 15. Which plotted point (A-H) is on the y-axis but is NOT the origin?
  Answer: Point
• 16. List all the plotted points (A-H) that are in Quadrant III.
  Answer:
• 17. What is the vertical distance (how many units up or down) between point A and point G?
  Answer: units
• 18. Which two plotted points (A-H) have the same y-coordinate?
  Answer: Points and
• 19. If you "reflect" point D (7, -7) across the y-axis (like in a mirror), what would its new coordinates be?
  Answer: (, )
• 20. Imagine a line connecting point F to the origin (0,0) and another line connecting point E to the origin (0,0). What kind of angle do these two lines form?
  Answer:
