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).

Front

What are the axes in a coordinate plane?

Back

The two axes are the x-axis (horizontal) and the y-axis (vertical).

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written in the form (x, y).

Front

What does the first number in an ordered pair represent?

Back

The first number represents the x-coordinate, which indicates the horizontal position on the coordinate plane.

Front

What does the second number in an ordered pair represent?

Back

The second number represents the y-coordinate, which indicates the vertical position on the coordinate plane.

Front

How do you identify a point on the coordinate plane?

Back

To identify a point, start at the origin (0,0), move along the x-axis to the x-coordinate, and then move vertically to the y-coordinate.

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

What is the y-axis?

Back

The y-axis is the vertical line on a coordinate plane where all points have the same x-coordinate.

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a coordinate plane where all points have the same y-coordinate.

Front

What is the significance of the quadrants in a coordinate plane?

Back

The coordinate plane is divided into four quadrants, each representing different signs of x and y coordinates.
