What is the origin in a coordinate system?

Back

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

How do you identify the coordinates of a point on a graph?

Back

The coordinates of a point on a graph are identified by its position relative to the x-axis and y-axis, expressed as an ordered pair (x, y).

How do you plot an ordered pair on a graph?

Back

To plot an ordered pair (x, y), start at the origin (0, 0), move x units along the x-axis, and then move y units up or down along the y-axis.
