Answer 2

Number of Rays Formed by 7 Points on a Line

To determine the number of rays formed by 7 points on a line, we need to understand the concept of rays and how they are formed.

A ray is a part of a line that has one endpoint and extends infinitely in one direction. In this case, we have 7 points on a line, and we want to know how many rays are formed with these points as their starting points.

Unfortunately, the search results provided do not directly address the specific question about the number of rays formed by 7 points on a line. However, we can use our knowledge of geometry to answer this question.

In general, when we have n points on a line, the number of rays formed is equal to n - 1.

Therefore, if we have 7 points on a line, the number of rays formed would be 7 - 1 = 6.

So, in this case, 6 rays would be formed with the 7 points as their starting points.
