1. The Coordinate Plane
Mr. Becvar
Colegio Nueva Granada

2. Vocabulary Words Coordinate plane – a grid system formed by two number
lines that cross at their zero points
Origin – the point at which the number lines cross.
This is point is (0,0)
Y-axis – the vertical number line
X-axis – the hoizontal number line
Quadrants – the x-axis and y-axis divide the coordinate
plane into four quadrants

3. The four quadrants of the coordinate plane.
Y-axis
Quadrant I
Quadrant II
X-axis
Quadrant IV
Quadrant III

4. Signs of the quadrants.
Y-axis
(+,+)
(-,+)
X-axis
(-,-)
(+,-)

5. The Ordered Pair
(5,10)
x- coordinate
y- coordinate

6. The Origin Point
Y-axis
Origin
Point
(0,0)
X-axis

7. Always start at the origin (0, 0) to plot a point.

8. Direction of Movement for the X-Coordinate
Y-axis
If the x-coordinate is positive move this way
If the x-coordinate is negative move this way
X-axis

9. Direction of movement for the Y-coordinate
Y-axis
If the y-coordinate is positive move this way
If the y-coordinate is negative move this way
X-axis

10. Name the given point.
Y-axis
(1,3)
(-2,1)
X-axis
(-5,-1)
(4,0)

11. How To Plot a Point on the Coordinate Plane
Y-axis
(4,4)
Next move on the Y-axis
X-axis
(-3,-1)
First move out on the
X-axis
