Introduction

In this article, we will explore the concept of dividing a line segment into three equal parts. We will use the endpoints of the line segment, A(2, 1) and B(11, 19), to find the coordinates of the two points that divide the segment into three equal parts. We will also describe the method used to find these coordinates.

Part a) Find the coordinates of the two points that divide the segment into three equal parts

To find the coordinates of the two points that divide the segment into three equal parts, we need to use the concept of proportional division. This concept states that if a line segment is divided into n equal parts, the coordinates of the points that divide the segment can be found by multiplying the coordinates of the endpoints by the ratio of the number of parts to the total number of parts.

Let's denote the coordinates of the two points that divide the segment into three equal parts as P and Q. We can use the following ratios to find the coordinates of P and Q:

P divides the segment into 1/3 parts, so its coordinates are (2 + (1/3)(11-2), 1 + (1/3)(19-1))
Q divides the segment into 2/3 parts, so its coordinates are (2 + (2/3)(11-2), 1 + (2/3)(19-1))

Now, let's calculate the coordinates of P and Q:

P = (2 + (1/3)(9), 1 + (1/3)(18))
P = (2 + 3, 1 + 6)
P = (5, 7)
Q = (2 + (2/3)(9), 1 + (2/3)(18))
Q = (2 + 6, 1 + 12)
Q = (8, 13)

Therefore, the coordinates of the two points that divide the segment into three equal parts are P(5, 7) and Q(8, 13).

Part b) Describe the method that you used in part a)

The method used to find the coordinates of the two points that divide the segment into three equal parts is based on the concept of proportional division. This concept states that if a line segment is divided into n equal parts, the coordinates of the points that divide the segment can be found by multiplying the coordinates of the endpoints by the ratio of the number of parts to the total number of parts.

To apply this concept, we need to follow these steps:

Determine the number of parts that the line segment is to be divided into. In this case, we want to divide the segment into three equal parts.
Calculate the ratio of the number of parts to the total number of parts. In this case, the ratio is 1/3 for the first point and 2/3 for the second point.
Multiply the coordinates of the endpoints by the ratio to find the coordinates of the points that divide the segment.
Simplify the expressions to find the final coordinates of the points.

By following these steps, we can use the concept of proportional division to find the coordinates of the two points that divide the segment into three equal parts.
