By the geometric definition of a line, it is represented by two points, and all points on the line are collinear, between or extrapolating to infinity from the straight line made by the two points. In other words, a line is straight, and can be represented by a binomial function (example: y=2x+1). A parabola is a function, but cannot be described mathematically as a line.
It could be a circle or a sphere
The metric of a geometric space is defined as the distance between two points.
An ellipse? The shape described is not an exactly describable geometric shape, (), and as far as I know there is no name for it.
