Jones BCE Ordered Pairs vocabulary

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 represents the x-coordinate, which indicates the position along the horizontal axis.

Front

What does the second number in an ordered pair represent?

Back

The second number represents the y-coordinate, which indicates the position along the vertical axis.

Front

What is the x-axis?

Back

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

Front

What is the y-axis?

Back

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

Front

What does it mean for lines to be perpendicular?

Back

Perpendicular lines intersect at a right angle (90 degrees).

Front

What does it mean for lines to be parallel?

Back

Parallel lines are lines in a plane that never meet and are always the same distance apart.

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 identify a point on a coordinate plane?

Back

To identify a point, use its ordered pair (x, y) to find its position by moving x units along the x-axis and y units along the y-axis.

Front

What is coordinate N if it is (6,6)?

Back

Coordinate N is the point located at (6, 6) on the coordinate plane.
