Points Title Card

A point is a location in space.

A point has no size or dimension. You’ll often see a dot representing a point.

What the dot represents is the location of the point.

A coordinate grid is useful for locating a point.

A Cartesian coordinate system has x- and y-axes.

A point has x and y coordinates in such a system.

The x-coordinate is the point’s location relative to the x-axis.

The y-coordinate is the point’s location relative to the y-axis.
