It is in its general form: 2x+7y-14 = 0
Points cannot be parallel to other points. A straight line joining two points is parallel to a straight line joining another pair of points if the gradient (slope) of the two lines is the same.
In coordinated geometry the points on a straight line will determine its equation.
A straight line joining points on a circle is called a "chord" of that circle. If the line happens to pass through the center of the circle, then it's a "diameter" of that circle. The question asked about "points" on a circle, so two points on the circumference of that circle are being considered. (No line can join more than two points of a circle.)
Sometimes you do, sometimes you don't. In the Euclidean plane. a straight line is the shortest distance between two points. Also, the equation of a straight line is simpler than that of curved lines. Finally, there is the Occam Rule which can be put as follows: when there are lots of possibilities to choose from, go for the simplest one. There are infinitely many curves (including a straight line) that can go through a pair of points.

The perpendicular bisector of the straight line joining the two points.
The definition is any chart where one or more points lie off the straight line joining the other points.

A chord is a straight line joining two points on the circumference of a circle.
If it is a straight line it must be in the same plane. Otherwise not necessarily.
The name of a straight line joining two points on the circumference of a circle is a chord.If the line passes through the the centre of the circle it is called a diameter
It is the straight line joining the two points, A and B.
