CARTESIAN COORDINATE SYSTEM ( GRADE 8 ) online exercise for | Live ... - Free Printable

Let's solve the worksheet step by step.

Understanding the Coordinate Plane

The coordinate plane has:
- The x-axis (horizontal) and y-axis (vertical).
- An ordered pair is written as (x, y).
- x = horizontal position (left/right)
- y = vertical position (up/down)

Positive x → right; Negative x → left
Positive y → up; Negative y → down

## Part 1: Tell what point is located at each ordered pair

We'll locate each point on the grid:

1. (3, -2) → Move 3 units right, 2 units down → Point B
2. (2, 3) → Move 2 right, 3 up → Point D
3. (-5, 5) → Move 5 left, 5 up → Point O
4. (-7, -8) → Move 7 left, 8 down → Point H
5. (-4, 4) → Move 4 left, 4 up → Point C
6. (-5, 0) → Move 5 left, 0 up/down → on x-axis → Point F

✔ Answers:
1. B
2. D
3. O
4. H
5. C
6. F

## Part 2: Write the ordered pair for each given point

Now we find coordinates of labeled points:

7. E → At (-3, -2) → (-3, -2)
8. M → At (0, -6) → (0, -6)
9. P → At (8, 0) → (8, 0)
10. G → At (7, 8) → (7, 8)
11. Q → At (-8, 0) → (-8, 0)
12. N → At (5, 5) → (5, 5)

✔ Answers:
7. (-3, -2)
8. (0, -6)
9. (8, 0)
10. (7, 8)
11. (-8, 0)
12. (5, 5)

## Part 3: Plot the following points on the coordinate grid

You are to plot these points on the graph:

13. S (-6, -3) → 6 left, 3 down → Plot at that location
14. T (2, -4) → 2 right, 4 down → Plot here
15. U (5, 8) → 5 right, 8 up → Plot here

> These points are not labeled on the original graph, so you would add them manually.

✔ Final Answer Summary:

#### Part 1: What point is at each ordered pair?
1. (3, -2) → B
2. (2, 3) → D
3. (-5, 5) → O
4. (-7, -8) → H
5. (-4, 4) → C
6. (-5, 0) → F

#### Part 2: Ordered pairs for each point
7. E → (-3, -2)
8. M → (0, -6)
9. P → (8, 0)
10. G → (7, 8)
11. Q → (-8, 0)
12. N → (5, 5)

#### Part 3: Plot the points
13. S (-6, -3) → Plot on grid
14. T (2, -4) → Plot on grid
15. U (5, 8) → Plot on grid

✔ Note: For Part 3, since this is a printed worksheet, you would physically plot the points on the grid using a pencil or marker.
