Coordinate Plane

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 coordinates of a point?

Back

Coordinates are a pair of numbers that define the position of a point on a coordinate plane, represented as (x, y). The first number (x) indicates the horizontal position, and the second number (y) indicates the vertical position.

Front

What is the origin in a coordinate plane?

Back

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

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 identify the quadrant of a point?

Back

To identify the quadrant of a point (x, y), check the signs of x and y: if both are positive, it's in Quadrant I; if x is negative and y is positive, it's in Quadrant II; if both are negative, it's in Quadrant III; if x is positive and y is negative, it's in Quadrant IV.

Front

What are the coordinates of Point I if it is located at (-2, -5)?

Back

The coordinates of Point I are (-2, -5).

Front

What is the x-coordinate of a point?

Back

The x-coordinate is the first number in an ordered pair (x, y) that indicates the horizontal position of the point on the coordinate plane.

Front

What is the y-coordinate of a point?

Back

The y-coordinate is the second number in an ordered pair (x, y) that indicates the vertical position of the point on the coordinate plane.

Front

What does it mean if a point has a negative x-coordinate?

Back

A negative x-coordinate indicates that the point is located to the left of the origin on the x-axis.

Front

What does it mean if a point has a negative y-coordinate?

Back

A negative y-coordinate indicates that the point is located below the origin on the y-axis.
