the answer is a 'ray'
It depends on what the name of the initial point is because that defines the direction of the ray. If the initial point is c, then the ray must be called cd, but if the initial point is d, then the ray must be called dc.

There is no end point, a ray is never ending but has a point to represent the beginning
A line with a dot at one end and an arrow at the other end is called a ray in geometry. A ray has a starting point (the dot) and extends infinitely in one direction (towards the arrow). It is often denoted by naming the starting point and any other point on the ray, such as "ray AB" if A is the starting point and B is another point on the ray. Rays are commonly used in geometric constructions and proofs.
That type of line would be called a ray.
the answer is a 'ray'
The point at the end of a ray is called the endpoint. It is the specific location where the ray ends or terminates.

The starting point in a race is called the starting line. The end point of a race is called the finish line.
