How many rays will be obtained if 3 points, 5 points, 100 points are marked on a straight line

Let’s find how many rays will turn out if we mark 3 points, 5 points, 100 points on a straight line:

if you mark one point on a straight line, then two rays will come out of it, one in one direction, the second in the opposite;

if there are 3 points, then there will be 3 * 2 = 6 rays;

if there are 5 points, then the rays will be 5 * 2 = 10;

if there are 100 points, then the rays will be 100 * 2 = 200.

Answer: 6 rays; 10 rays; 200 rays.
