In a two-dimensional coordinate plane, there are only two axes, the x-axis and the y-axis. The axes are perpendicular and intersect at the origin. Each axis defines one dimension of the coordinate plane.
We can graph the third axis perpendicular to both the x-axis and y-axis.
The z-axis determines the third dimension. This means that the coordinate system formed by the x-axis, y-axis, and z-axis is three-dimensional. Let's fill in the blank.
A three-dimensional coordinate system can be formed by passing a z-axis perpendicular to both the x-axis and the y-axis at the origin.
