Coordinate Plane Review

Front

What is the coordinate plane?

Back

The 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 (x, y).

Front

What are the four quadrants of the 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

What does it mean to reflect a point over the x-axis?

Back

Reflecting a point over the x-axis means to create a new point that has the same x-coordinate but the opposite y-coordinate. For example, reflecting (3, 4) results in (3, -4).

Front

What is the ordered pair for the origin?

Back

The ordered pair for the origin is (0, 0).

Front

How do you determine the quadrant of a point with positive x and negative y coordinates?

Back

A point with positive x and negative y coordinates is located in Quadrant IV.

Front

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

Back

The area of the rectangle is 24 units squared (Area = length × width).

Front

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

Back

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

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, such as (0, y) or (x, 0).

Front

What are the coordinates of point E if it is located 2 units up from the origin?

Back

The coordinates of point E are (0, 2).

Front

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

Back

The point (-3, 12) is located in Quadrant II.
