1. Graphing on the Coordinate Plane

2. Coordinate Plane
The plane formed when 2 perpendicular number lines intersect at their zero points 5 4 3 2 1 -1 -4 -5 -1 -3 -2 1 2 3 4 5 -2 -3 -4 -5

3. Coordinate Plane
The plane formed when 2 perpendicular number lines intersect at their zero points
The vertical line is called the
y-axis
The horizontal line is called the
x-axis
Where the lines intersect is called “the origin”

4. - Coordinate Plane + X values to the right of the origin are positive
X values to the left of the origin are negative - +

5. - Coordinate Plane + y values above the origin are positive
y values below the origin are negative + -

6. I II IV III Coordinate Plane
The x and y axis divide the coordinate plane into 4 regions called “quadrants”
x is negative,
y is positive II I
x is positive,
y is positive
x is negative,
y is negative
III IV
x is positive,
y is negative

7. Ordered Pair
A point on the coordinate plane consists of 2 values – the first is the x-coordinate, the second is the y-coordinate y
Starting at the origin, the point is 2 spaces to the right
(2,3)
x = +2 x
Then the point is 3 spaces up
y = +3

8. Ordered Pair (-4,2) x = - 4 y = +2
A point on the coordinate plane consists of 2 values – the first is the x-coordinate, the second is the y-coordinate y
Starting at the origin, the point is 4 spaces to the left
(-4,2)
x = - 4 x
Then the point is 2 spaces up
y = +2

10. Name the Ordered Pair y
