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 axes in a coordinate plane?

Back

The axes in a coordinate plane are the x-axis (horizontal) and the y-axis (vertical). They intersect at the origin (0, 0).

Front

What is an ordered pair?

Back

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

Front

What does the first number in an ordered pair represent?

Back

The first number in an ordered pair represents the x-coordinate, which indicates the horizontal position of the point.

Front

What does the second number in an ordered pair represent?

Back

The second number in an ordered pair represents the y-coordinate, which indicates the vertical position of the point.

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 ordered pair (0, 0).

Front

How do you plot a point on a coordinate plane?

Back

To plot a point, start at the origin (0, 0). Move horizontally to the x-coordinate and then vertically to the y-coordinate.

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

What is the distance between the points (2, 3) and (2, 5)?

Back

The distance is 2 units, as they have the same x-coordinate and differ in the y-coordinate.

Front

What is the distance between the points (1, 1) and (4, 5)?

Back

The distance is calculated using the distance formula: √((x2 - x1)² + (y2 - y1)²) = √((4 - 1)² + (5 - 1)²) = √(9 + 16) = √25 = 5.
