Coordinate Plane Review

Front

What is the definition of an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point in a coordinate plane, written in the form (X, Y).

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 reflect a point over the x-axis?

Back

To reflect a point (X, Y) over the x-axis, change the sign of the y-coordinate, resulting in the point (X, -Y).

Front

How do you reflect a point over the y-axis?

Back

To reflect a point (X, Y) over the y-axis, change the sign of the x-coordinate, resulting in the point (-X, Y).

Front

What is the formula for calculating the area of a rectangle?

Back

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

Front

What is the area of a shape with a length of 6 units and a width of 4 units?

Back

The area is 24 square units (6 × 4 = 24).

Front

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

Back

The coordinate of the origin is (0, 0).

Front

How do you identify the quadrant of a point in the coordinate plane?

Back

The quadrant can be identified based on the signs of the x and y coordinates: Quadrant I (positive, positive), Quadrant II (negative, positive), Quadrant III (negative, negative), Quadrant IV (positive, negative).

Front

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

Back

The distance formula is: Distance = √((x2 - x1)² + (y2 - y1)²).
