Coordinate Plane Flashcard

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 of numbers (x, y).

What does the ordered pair (x, y) represent?

Back

The ordered pair (x, y) represents the position of a point on the coordinate plane, where 'x' is the horizontal distance from the origin and 'y' is the vertical distance from the origin.

How do you find the perimeter of a rectangle?

Back

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

What is the formula for the area of a rectangle?

Back

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

What does it mean to plot a point on the coordinate plane?

Back

To plot a point means to mark its location on the coordinate plane based on its ordered pair (x, y).

How do you move to plot the point (4, -12)?

Back

To plot the point (4, -12), move 4 units to the right on the x-axis and then 12 units down on the y-axis.

What is the distance between two points on the coordinate plane?

Back

The distance between two points can be found using the distance formula: d = √((x2 - x1)² + (y2 - y1)²).

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. It serves as the reference point for all other points on the plane.

How do you identify the coordinates of a point?

Back

The coordinates of a point are identified by its position relative to the x-axis and y-axis, expressed as (x, y).

What is the x-axis?

Back

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