Understanding the Section Formula: A Guide for SEO and Content Optimization

When working with coordinate geometry, one of the most useful tools is the section formula. This formula is pivotal in dividing a line segment into specified ratios and finding the coordinates of the point of division. Let's consider a problem where point R lies on the line segment AB with given coordinates A(3, 6) and B(9, 10), and divides AB in the ratio 3:-2. This article will walk you through the application of the section formula, ensuring that the content is optimized for SEO and meets the standards expected by Google.

Introduction to the Section Formula

The section formula is a powerful mathematical tool that helps in finding the coordinates of a point that divides a line segment in a given ratio. The formula is derived from the concept of weighted averages, where the distance of the point from the endpoints of the segment is proportional to the given ratio.

Deriving the Section Formula

For a line segment AB with endpoints A(x1, y1) and B(x2, y2) and a point R dividing AB in the ratio m:n, the coordinates of R can be found using the following formula:

Step-by-Step Calculation

Determine the given coordinates of A and B.

A(3, 6)

B(9, 10)

Identify the ratio in which the point R divides AB.

Ratio 3:-2

Apply the section formula to calculate the coordinates of R.

Coordinates of R (left(frac{mx_2 nx_1}{m n}, frac{my_2 ny_1}{m n}right))

In this case:

x1 3, y1 6 (coordinates of A)

x2 9, y2 10 (coordinates of B)

m 3, n -2 (ratio in which R divides AB)

Coordinates of R

(left(frac{3 cdot 9 (-2) cdot 3}{3 (-2)}, frac{3 cdot 10 (-2) cdot 6}{3 (-2)}right))

(left(frac{27 - 6}{1}, frac{30 - 12}{1}right))
