The Directed Line Segment: Finding the Coordinates of Point M

In geometry, a directed line segment is a line segment with a specific direction and a starting point, known as the initial point, and an ending point, known as the terminal point. The directed line segment from L to N has endpoints L(-6, 2) and N(5, -3). In this article, we will discuss how to find the x- and y-coordinates of point M, which partitions the directed line segment.

What is a Directed Line Segment?

A directed line segment is a line segment with a specific direction and a starting point, known as the initial point, and an ending point, known as the terminal point. The directed line segment from L to N has endpoints L(-6, 2) and N(5, -3). The direction of the line segment is from L to N.

Partitioning a Directed Line Segment

Partitioning a directed line segment means dividing the line segment into two equal parts. To find the coordinates of point M, which partitions the directed line segment, we need to find the midpoint of the line segment.

Finding the Midpoint of a Line Segment

The midpoint of a line segment is the point that divides the line segment into two equal parts. To find the midpoint of a line segment, we need to find the average of the x-coordinates and the y-coordinates of the endpoints.

Formula for Finding the Midpoint

The formula for finding the midpoint of a line segment is:

M = ((x1 + x2)/2, (y1 + y2)/2)

where (x1, y1) and (x2, y2) are the coordinates of the endpoints.

Applying the Formula

To find the coordinates of point M, which partitions the directed line segment, we need to apply the formula:

M = ((-6 + 5)/2, (2 + (-3))/2)

M = ((-1)/2, (-1)/2)

M = (-0.5, -0.5)

In conclusion, the directed line segment from L to N has endpoints L(-6, 2) and N(5, -3). To find the coordinates of point M, which partitions the directed line segment, we need to find the midpoint of the line segment. The formula for finding the midpoint of a line segment is:

M = ((x1 + x2)/2, (y1 + y2)/2)

where (x1, y1) and (x2, y2) are the coordinates of the endpoints. Applying the formula, we get:

M = ((-6 + 5)/2, (2 + (-3))/2)

M = ((-1)/2, (-1)/2)

M = (-0.5, -0.5)

Therefore, the x- and y-coordinates of point M are -0.5 and -0.5, respectively.

Suppose we have a directed line segment with endpoints A(2, 4) and B(6, 8). To find the coordinates of point C, which partitions the directed line segment, we need to apply the formula:

C = ((2 + 6)/2, (4 + 8)/2)

C = ((8)/2, (12)/2)

C = (4, 6)

Therefore, the x- and y-coordinates of point C are 4 and 6, respectively.

In conclusion, directed line segments are an important concept in mathematics and have many applications in real-world problems. The formula for finding the midpoint of a line segment is:

M = ((x1 + x2)/2, (y1 + y2)/2)

where (x1, y1) and (x2, y2) are the coordinates of the endpoints. Applying the formula, we can find the coordinates of point M, which partitions the directed line segment.
