Which of the following is the most precise definition of a line segment based on the notions of "point" and "line"? A. A line segment is a figure composed of two points and a line. B. A line segment is a portion of a line that lies between two points C. A line segment is a portion of a line that connects two distinct points on the line without extending beyond them D. A line segment is composed of all the points on a line that are greater than a distance d from a given point not on the line

A line is a simple geometric shape that extends in both the directions, but a line segment has two defined endpoints. Both the figures are also different from a ray, as a ray has only one endpoint and extend infinitely in one direction.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
