That's called the "distance" between the points.
One measure of distance between them.
Yes, they can exist.
A straight line of infinite length!
The shortest path between two points
The Length of a path between two points is known as distance.
Distance is the path between two points.
The length of the path followed during motion is the total distance covered by an object moving from one point to another. It can be calculated by summing up the distances between consecutive points along the path.
The distance measured between two points in units of length is called the linear distance. It signifies the length or span between two specific points along a straight line or a path.
That's called the "distance" between the points.
The length of the path an object moves along is the total distance covered by the object from its starting point to its ending point. This can be calculated by summing the distances traveled along each segment of the path.
Distance is a measure of how far an object has moved from its starting point. It is a scalar quantity that specifies the length between two points along the path followed. Distance does not require a specific direction, only the magnitude of the path traveled.

The displacement of a satellite when it completes one round along its circular path is zero. This is because the displacement is the shortest distance between the starting and ending points, and in a circular path, the starting and ending points are the same.
A line segment is a straight path between two points on a line. Its length is the distance between those two points.
Distance is the total length of the path traveled between two points, while displacement is the direct line distance between those points. Distance can be equal to or greater than the magnitude of displacement if the path followed is not a straight line.
Distance travelled by a body is the total length of the path covered, while displacement is the shortest distance between the initial and final positions of the body (measured in a straight line). In a diagram, imagine a curved path with turns and loops - the total length of this path is the distance travelled, while the straight line connecting the start and end points represents the displacement, which is the shortest distance between the two points.
