Coordinate Plane Review

Front

What is the coordinate plane?

Back

A two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis), used to locate points using ordered pairs (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

What are coordinates?

Back

A pair of numbers (x, y) that define the position of a point on the coordinate plane.

Front

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

Back

Change the sign of the x-coordinate. For example, the reflection of (x, y) is (-x, y).

Front

What is the distance formula?

Back

The distance between two points (x1, y1) and (x2, y2) is given by the formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the area of a rectangle?

Back

Area = length × width, measured in square units.

Front

How do you find the midpoint between two points?

Back

The midpoint M between points (x1, y1) and (x2, y2) is M = ((x1 + x2)/2, (y1 + y2)/2).

Front

What is a square?

Back

A quadrilateral with four equal sides and four right angles.

Front

What are the coordinates of the origin?

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect.

Front

What does it mean for a point to be in 'No Quadrant'?

Back

A point is in 'No Quadrant' if it lies on one of the axes (x-axis or y-axis) and does not fall into any of the four quadrants.
