Coordinate plane review

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 of numbers (x, y).

Front

What are the four quadrants of a coordinate plane?

Back

The four quadrants are: Quadrant I (x > 0, y > 0), Quadrant II (x < 0, y > 0), Quadrant III (x < 0, y < 0), Quadrant IV (x > 0, y < 0).

Front

How do you find the distance between two points on a coordinate plane?

Back

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

Front

What is the distance between points (3, -5) and (3, -8)?

Back

3 units.

Front

In which quadrant is the point (-3, 12)?

Back

Quadrant II.

Front

Which quadrant contains the point (2, 5)?

Back

Quadrant I.

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2(length + width).

Front

What is the perimeter of a shape with sides measuring 5 units, 5 units, 5 units, and 5 units?

Back

20 units.

Front

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

Back

The coordinates are given as an ordered pair (x, y), where 'x' is the horizontal position and 'y' is the vertical position.

Front

What does it mean for a point to be on the x-axis?

Back

A point is on the x-axis if its y-coordinate is 0, represented as (x, 0).
