In Exercises $3-6,$ fiind the coordinates of point $\mathrm{P}$ along the directed line segment $\mathrm{AB}$ so that $\mathrm{AP}$ to $\mathrm{PB}$ is the given ratio. (See Example 1.)

$$A(8,0), B(3,-2) ; 1 \text { to } 4$$

Key Concepts

Coordinate Geometry

Coordinate geometry, or analytic geometry, involves using algebraic techniques to study geometric figures. It allows for precise calculations involving points, lines, and segments on a coordinate plane, making it possible to resolve problems involving distances, midpoints, and sections divided in given ratios.

Ratio Division

Ratio division is the process of dividing a line segment into parts that reflect a given proportional relationship. In coordinate geometry, this concept is essential for determining the exact coordinates of a point that splits the segment in accordance with the prescribed ratio.

Directed Line Segment

A directed line segment is one that has a specific orientation from one endpoint to the other. This concept is important when working with ratios, as the direction dictates how the ratio is applied and which endpoint corresponds to which part of the division.

Section Formula

The section formula is a fundamental tool in coordinate geometry used to determine the coordinates of a point that divides a line segment joining two points in a given ratio. It uses a weighted average of the endpoint coordinates based on the specified division ratio, providing a systematic way to calculate the location of the intermediate point.
