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), used to locate points using ordered pairs.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point on a coordinate plane, written in the form (x, y), where x is the horizontal position and y is the vertical position.

Front

What does the x-coordinate represent in an ordered pair?

Back

The x-coordinate represents the horizontal position of a point on the coordinate plane.

Front

What does the y-coordinate represent in an ordered pair?

Back

The y-coordinate represents the vertical position of a point on the coordinate plane.

Front

How do you identify the coordinates of a point on a coordinate plane?

Back

To identify the coordinates of a point, locate the point on the plane, determine how far it is from the y-axis (x-coordinate) and how far it is from the x-axis (y-coordinate), and write them as an ordered pair (x, y).

Front

What is the significance of 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). It serves as the reference point for all other points on the plane.

Front

If a point is located at (3, 5), what does this indicate about its position?

Back

The point (3, 5) is located 3 units to the right of the origin along the x-axis and 5 units up along the y-axis.

Front

How do you move from one point to another on a coordinate plane?

Back

To move from one point to another, determine the change in the x-coordinate (horizontal movement) and the change in the y-coordinate (vertical movement), and apply these changes to the original coordinates.

Front

What is the result of moving right on the coordinate plane?

Back

Moving right on the coordinate plane increases the x-coordinate of a point.

Front

What is the result of moving left on the coordinate plane?

Back

Moving left on the coordinate plane decreases the x-coordinate of a point.
