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). It is used to locate points using ordered pairs (x, y).

Front

What are the four quadrants of a coordinate plane?

Back

The four quadrants are: 1st Quadrant (x > 0, y > 0), 2nd Quadrant (x < 0, y > 0), 3rd Quadrant (x < 0, y < 0), 4th Quadrant (x > 0, y < 0).

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on the coordinate plane, written in the form (x, y).

Front

How do you identify the quadrant of a point (x, y)?

Back

To identify the quadrant, check the signs of x and y: 1st Quadrant (both positive), 2nd Quadrant (x negative, y positive), 3rd Quadrant (both negative), 4th Quadrant (x positive, y 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).

Front

What are the coordinates of the origin?

Back

The coordinates of the origin are (0, 0).

Front

What does it mean for a point to be in the 4th quadrant?

Back

A point in the 4th quadrant has a positive x-coordinate and a negative y-coordinate.

Front

What does it mean for a point to be in the 3rd quadrant?

Back

A point in the 3rd quadrant has both x and y coordinates negative.

Front

If a point has coordinates (3, 0), where is it located?

Back

The point (3, 0) is located on the x-axis, to the right of the origin.

Front

If a point has coordinates (0, -5), where is it located?

Back

The point (0, -5) is located on the y-axis, below the origin.
