2. Quadrant II where x is negative and y is positive
y axis
Quadrant II where x is negative and y is positive
Quadrant I where both x and y are positive
x axis
origin
Quadrant IV where x is positive and y is negative
Quadrant III where both x and y are negative

3. (x,y)
The 1st coordinate, or x, tells us how far to go left or right.
Positive= Right
Negative = Left.
The 2nd number, or y, tells us how far to go up or down Positive = up Negative = down.

4. Plot the x number first moving to the left when the number is negative.y 3 2
(-3, -2) 1 x -1 -2 -3 -3 -2 -1 1 2 3

5. Plot the y number moving from your new position down 2 when the number is negative.3 2
(-3, -2) 1 x -1 -2 -3 -3 -2 -1 1 2 3

6. How to Plot in 4 Quadrants
When x is positive and y is negative, plot the coordinate in this manner. y 3 2
(2, -2) 1 x -1 -2 -3 -3 -2 -1 1 2 3

7. How to Plot in 4 Quadrants
When x is negative and y is positive, plot the coordinate in this manner. y 3 2
(-2, 2) 1 x -1 -2 -3 -3 -2 -1 1 2 3

8. Plot This Coordinate
(-3, -3) y 3 2 1 x -1 -2 -3 -3 -2 -1 1 2 3

9. Plot This Coordinate
(-1, 2) y 3 2 1 x -1 -2 -3 -3 -2 -1 1 2 3

10. Plot This Coordinate
(1, -1) y 3 2 1 x -1 -2 -3 -3 -2 -1 1 2 3

11. Plot This Coordinate
(2, -2) y x

12. Plot This Coordinate
(-3, -2) y x

13. WRITE THE COORDINATES FOR EACH POINT
B: (4, 6)
C: (2, 1)
D: (-4, 3)
E: (-5, 0)
F: (-3, -2)
G: (0, -4)
H: (4, -4)

14. Horizontally Vertically Equally One cm apart Question #1: Grid Lines
The lines of a grid are spaced:
Horizontally
Vertically
Equally
One cm apart
The best answer is:
Equally.
Lines run vertically and horizontally. The distance between them is arbitrary, but must be equal.

15. Question #2: Axes Horizontal Vertical Parallel Perpendicular
Coordinate system axes are:
Horizontal
Vertical
Parallel
Perpendicular
The best answer is:
Perpendicular.
One axis is horizontal; the other is vertical. They meet at a 90° angle, like an upside down T.

16. Question #3: Origin (0,0) {0,0} (1,1) {1,1}
The coordinates of the origin are:
(0,0)
{0,0}
(1,1)
{1,1}
The best answer is:
(0,0)
The origin is the point where the axes intersect; the zero point. It serves as a relative reference for all other addresses.

17. Question 4: Addresses North South Vertical Horizontal
The 7 in the address (5,7) indicates units:
The best answer is:
Vertical
Each address on a plane coordinate system has two values. The first indicates units horizontally from the origin. The second value indicates units vertical from the origin. In (5,7), the point is 7 units vertically offset from (0,0).

18. Question #5: Plotting (9,8) (8,9) (10, 9) (9,10)
The location of the point shown is:
(9,8)
(8,9)
(10, 9)
(9,10) ?
The best answer is: (8, 9) From the origin, the first value is units horizontal and the second value is units vertical. ?

19. Question #6: Quadrants (9,2) I State the coordinate and the quadrant.
(4,-3) IV
(4,3) II
(2,9) III
State the coordinate and the quadrant. IV I II
III
The best answer is:(4,-3) IV Below zero (the origin) is minus units. Quadrants are indicated in Roman Numerals.
