To determine a trajectory line, only two points are needed. These two points can be used to calculate the slope, which represents the direction and angle of the trajectory. Additional points can be used to further refine the trajectory line and estimate its accuracy.
The answer depends on the sort of trajectory. If it isthe trajectory of a projectile, affected only by gravity then 3 points are enough. As soon as you add other forces: such a drag or continued propulsion, the number of points required increases.
Two distinct (different) points are needed to determine a line.
2 points determine a line.
A plane can be determined by three points, as long as the three points do not lie along a single line.
3 points which do not all lie on the same line.
2 points

Two. Two points determine a line. Three points determine a plane.
Infinitely many. The trajectory of a typical space mission may be adjusted several hundred times and all these changes need to be accommodated in the set of points.
A line contains an infinite number of points but it takes only two points to determine a line.
You need two points to determine a line. A single point can have an infinite number of lines passing through it.
2 points determine a line.
A plane can be determined by three points, as long as the three points do not lie along a single line.
3 points which do not all lie on the same line.
Two points determine a line. Also there is one and only line perpendicular to given line through a given point on the line,. and There is one and only line parallel to given line through a given point not on the line.
No. Three points do. Two points determine a line.
