The intersection of two lines is always a point or the line itself. The intersection of a line with plane also the same as above.

The xy or Cartesian or coordinate plane.
It works out that the point of intersection is at (-4, -3.5) on the Cartesian plane.
The intersection of a sphere with a plane is a point, or a circle.
It is simply called a point in the coordinate or Cartesian plane.
The Cartesian plane
The intersection of a line and a plane can result in either a single point, if the line passes through the plane, or no intersection at all if the line is parallel to the plane and does not touch it. In some cases, if the line lies entirely within the plane, every point on the line will be an intersection point. Thus, the nature of the intersection depends on the relative positions of the line and the plane.

You do not have 3 coordinates in the Cartesian plane. The Cartesian plane is a plane and is therefore 2 dimensional. In 2 dimensional space you require only 2 coordinates. 3 coordinates are required to locate a point in 3-dimensional space but then it cannot be a Cartesian PLANE.
The 'abscissa' is the x coordinate on the Cartesian plane and the 'ordinate' is the y coordinate on the Cartesian plane
Unless the line is a subset of the plane, the intersection is a point.
