Coordinate Plane 2

Front

What is the coordinate plane?

Back

A two-dimensional surface where points are defined by pairs of numbers (x, y).

Front

What are the four quadrants of the coordinate plane?

Back

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 (x1, y1) and (x2, y2)?

Back

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

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2(length + width).

Front

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

Back

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

Front

What does it mean for a point to be in Quadrant I?

Back

Both x and y coordinates are positive.

Front

What does it mean for a point to be in Quadrant II?

Back

The x coordinate is negative and the y coordinate is positive.

Front

What does it mean for a point to be in Quadrant III?

Back

Both x and y coordinates are negative.

Front

What does it mean for a point to be in Quadrant IV?

Back

The x coordinate is positive and the y coordinate is negative.
