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). Each point on the plane is defined by an ordered pair (x, y).

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).

How do you find the perimeter of a rectangle?

Back

To find the perimeter of a rectangle, add the lengths of all four sides or use the formula: P = 2(length + width).

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: A = length × width.

Front

What does the x-coordinate represent?

Back

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

Front

What does the y-coordinate represent?

Back

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

Front

How do you plot the point (3, 2) on a coordinate plane?

Back

Start at the origin (0, 0), move right 3 units (x-coordinate), and then move up 2 units (y-coordinate).

Front

What is the distance formula for two points (x1, y1) and (x2, y2)?

Back

The distance between two points is calculated using the formula: D = √((x2 - x1)² + (y2 - y1)²).

Front

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

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect, serving as the reference point for all other points.

Front

What is the difference between the x-axis and y-axis?

Back

The x-axis is the horizontal line on the coordinate plane, while the y-axis is the vertical line.
