Solution

Solution Steps

Step 1: Understanding the concept of a line

A line in geometry is defined as a straight one-dimensional figure that extends infinitely in both directions. Through any two distinct points, only one unique line can be drawn. This is a fundamental property of Euclidean geometry.

Step 2: Importance of graphing three or more points

Graphing three or more points before drawing a line through them is helpful because it allows us to verify the linearity of the relationship between the points. If all three points lie on the same straight line, it confirms that the relationship is indeed linear. If they do not, it indicates that the relationship might be non-linear or that there is an error in the data.

Step 3: Practical application

In practical applications, such as data analysis or experimental results, plotting multiple points helps to ensure the accuracy and reliability of the line being drawn. It also helps to identify any outliers or anomalies in the data.

Final Answer

Graphing three or more points before drawing a line through them is helpful because it verifies the linearity of the relationship and ensures the accuracy of the line. If all points lie on the same straight line, the relationship is confirmed to be linear. \\(\boxed{\text{Graphing three or more points ensures the accuracy and linearity of the line.}}\\)
