If both points have either the same 'x' value or the same 'y' value,
then they both lie on the same grid line.
The Cartesian coordinates.
They represent two points.
If both points have either the same 'x' value or the same 'y' value, then they both lie on the same grid line.
A coordinate plane
Ordered pairs are used to locate points on the coordinate plane.
Yes, ordered pairs identify points in a coordinate plane. If that doesn't answer your question, please restate it (say it another way).
The Cartesian coordinates.
They represent two points.
You can locate any point on the coordinate plane by an ordered pair of numbers (x,y), called the coordinates.
If both points have either the same 'x' value or the same 'y' value, then they both lie on the same grid line.
If both points have either the same 'x' value or the same 'y' value, then they both lie on the same grid line.
In order to draw a straight line, two unique ordered pairs are needed. This is because two unique points determine a line and an ordered pair represents a point.

A coordinate plane
Ordered pairs are used to locate points on the coordinate plane.
The coordinates of all points in the coordinate plane consist of ordered pairs of numbers.
A coordinate plane has infinitely many ordered pairs: each and every point in the plane is represented by an ordered pair. There may be a small number of points that are identified for a specific reason: for example the vertices of a triangle or quadrilateral and so you may have a few ordered pairs that are specifically labelled.
