Graphing Ordered Pairs

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent 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 horizontal position on the coordinate plane.

Front

What does the second number in an ordered pair represent?

Back

The second number represents the y-coordinate, which indicates the vertical position on the coordinate plane.

Front

What is the coordinate plane?

Back

The coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

Front

What is the x-axis?

Back

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

Front

What is the y-axis?

Back

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

Front

How do you plot a point on the coordinate plane?

Back

To plot 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 the coordinate plane?

Back

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

Front

What is the distance between two points on the same vertical line?

Back

The distance is the absolute difference between their y-coordinates.

Front

What is the distance between two points on the same horizontal line?

Back

The distance is the absolute difference between their x-coordinates.
