Ordered Pairs and Coordinate Grid

Coordinate Plane and Ordered Pairs Review

​Coordinate Plane

​The x-axis is the horizontal axis


The y-axis is the vertical axis

Origin

The x-axis and y-axis intersect at a point called the ORIGIN.

The origin is located at (0,0).

Multiple Choice

The coordinate plane is divided by a horizontal number line called ______________

• x-axis

• y-axis

• origin

• quadrant

Multiple Choice

The coordinate plane is divided by a vertical number line called ______________

• x-axis

• y-axis

• origin

• quadrant

Plotting Points

Although there are two coordinates given for an ordered pair, it is a series of these two movements that result in one plotted point.

(x, y)

First follow the x to move left/right,

Then follow the y to move up/down.

Plotting Points

(x, y)

If x is negative...move to the left

If x is positive...move to the left


If y is negative...move down

If y is positive...move up
