Coordinate Plane Flashcard

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 (x, y).

Front

What does an ordered pair represent in a coordinate plane?

Back

An ordered pair (x, y) represents a specific point on the coordinate plane, 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 number line in a coordinate plane, where the value of 'y' is zero.

Front

What is the y-axis?

Back

The y-axis is the vertical number line in a coordinate plane, where the value of 'x' is zero.

Front

What is the origin in a coordinate plane?

Back

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

Front

What are quadrants in a coordinate plane?

Back

Quadrants are the four sections of the coordinate plane created by the x-axis and y-axis. They are labeled as Quadrant I, II, III, and IV.

Front

How do you plot a point on a coordinate plane?

Back

To plot 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 significance of the first number in an ordered pair?

Back

The first number in an ordered pair represents the position along the x-axis.

Front

What is the significance of the second number in an ordered pair?

Back

The second number in an ordered pair represents the position along the y-axis.

Front

How do you identify the coordinates of a point on a graph?

Back

The coordinates of a point are identified by reading the x-value from the horizontal axis and the y-value from the vertical axis.
