A set of points on a straight line are called 'collinear points'.
Collinear Points.
A straight line is a line with the property that, if you pick any two points on the line and connect these points with a straight line, then every point on this new line lies on the original line.
A straight line is the shortest distance between two points, a line is the delineation of a connection between two or more points.
The shortest distance between two points is... a straight line.
In coordinated geometry the points on a straight line will determine its equation.
The definition is any chart where one or more points lie off the straight line joining the other points.
A line segment is a straight line with end points
Collinear points are points on the same straight line.
Points on the same line are called collinear points.
No because a defined straight line has 2 end points.
If you mean a straight line that does not extend BEYOND it's two end points, then that would be a 'line segment.'
