Coordinate Plane Concepts

Front

What direction does the y-axis go?

Back

UP and DOWN (or vertical)

Front

What are the 2 "axes" on the coordinate plane?

Back

They are number lines. One is the x-axis, the other is the y-axis.

Front

Origin in a coordinate plane

Back

The point where the x-axis and y-axis intersect, represented by (0,0).

Front

Quadrants of the coordinate plane

Back

Quadrant 1 (+,+), Quadrant 2 (-,+), Quadrant 3 (-,-), Quadrant 4 (+,-).

Front

Positive direction of the x-axis

Back

To the right of the origin.

Front

Negative direction of the x-axis

Back

To the left of the origin.

Front

Sign of coordinates in Quadrant I

Back

Both x and y are positive (+,+).

Front

Sign of coordinates in Quadrant III

Back

Both x and y are negative (-,-).

Front

What is a coordinate point?

Back

An ordered pair (x, y) that represents a location on the coordinate plane.
