Coordinate Plane Graphing Notes

The document describes coordinate planes and ordered pairs. It defines a coordinate plane as having perpendicular x and y axes that intersect at the origin. Ordered pairs (x,y) are used to represent points in the plane by giving the number of units from the origin along the x and y axes. Common features like quadrants and labeling points with letters are also outlined.

Coordinate Plane Graphing

Coordinate plane - a coordinate system formed by the intersection


of a horizontal number line, called the x – axis , and a vertical
number line called the y-axis .

Ordered Pair – a pair of numbers that can be used to represent a point


in the coordinate plane, often expressed as ( x , y ) .

The first coordinate, x, of an ordered pair is the x - coordinate .


It tells how far left or right to move from the origin

The second coordinate, y, of an ordered pair is the y - coordinate .


It tells how far up or down to move from the origin

Quadrants - the four regions that the coordinate plane is divided into.

Write the order pairs that correspond to the points labeled.

Coordinate Plane

Coordinate plane - a coordinate system formed by the intersection


of a horizontal number line, called the x – axis , and a vertical
number line called the y-axis .

Points are labeled with capital letters .

Ordered Pair – a pair of numbers that can be used to represent a point


in the coordinate plane, often expressed as ( x , y ) .

The first coordinate, x, of an ordered pair is the x - coordinate .


It tells how far left or right to move from the origin

The second coordinate, y, of an ordered pair is the y - coordinate .


It tells how far up or down to move from the origin

Quadrants - the four regions that the coordinate plane is divided into.

The graph of (x,y) is the point in the plane that corresponds
to the ordered pair (x , y ).

Write the order pairs that correspond to the points labeled.
