Coordinate Planes

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). It is used to locate points using ordered pairs.

Front

What are ordered pairs?

Back

Ordered pairs are pairs of numbers used to locate points on a coordinate plane, written in the form (x, y), where x is the horizontal position and y is the vertical position.

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a coordinate plane, where the y-coordinate is zero.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a coordinate plane, where the x-coordinate is zero.

Front

What is the origin in a coordinate plane?

Back

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

Front

How do you plot a point on a coordinate plane?

Back

To plot a point, start at the origin (0, 0). Move horizontally to the x-coordinate and then vertically to the y-coordinate.

Front

What does the point (3, 2) represent on a coordinate plane?

Back

The point (3, 2) represents a location that is 3 units to the right of the origin and 2 units up.

Front

What is the first quadrant in a coordinate plane?

Back

The first quadrant is the area where both x and y coordinates are positive, located in the top right section of the coordinate plane.

Front

What is the second quadrant in a coordinate plane?

Back

The second quadrant is the area where x coordinates are negative and y coordinates are positive, located in the top left section of the coordinate plane.

Front

What is the third quadrant in a coordinate plane?

Back

The third quadrant is the area where both x and y coordinates are negative, located in the bottom left section of the coordinate plane.
