Coordinate Planes

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 does the x-axis represent?

Back

The x-axis represents the horizontal line on a coordinate plane where the y-coordinate is zero.

Front

What does the y-axis represent?

Back

The y-axis represents the vertical line on a coordinate plane where the x-coordinate is zero.

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

How do you identify a point on the coordinate plane?

Back

To identify a point, start at the origin (0,0), move along the x-axis to the x-coordinate, and then move vertically to the y-coordinate.

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

What is the significance of the first number in an ordered pair?

Back

The first number in an ordered pair represents the position along the x-axis.

Front

What is the significance of the second number in an ordered pair?

Back

The second number in an ordered pair represents the position along the y-axis.

Front

What quadrant is located at (5, 3)?

Back

(5, 3) is located in Quadrant I, where both x and y coordinates are positive.

Front

What quadrant is located at (-4, 2)?

Back

(-4, 2) is located in Quadrant II, where x is negative and y is positive.
