Introduction

In mathematics, the midpoint of a line segment is the point that divides the segment into two equal parts. It is an essential concept in geometry and is used to find the midpoint of a line segment with given endpoints. In this article, we will learn how to find the midpoint of a segment with the given endpoints ${(0, -4)}$ and ${(9, 10)}$ .

What is a Midpoint?

A midpoint is a point that lies on a line segment and divides it into two equal parts. It is the average of the x-coordinates and the y-coordinates of the endpoints of the segment. The midpoint formula is used to find the midpoint of a line segment with given endpoints.

Midpoint Formula

The midpoint formula is given by:

${(x_m, y_m) = \left(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}\right)}$

where ${(x_1, y_1)}$ and ${(x_2, y_2)}$ are the given endpoints of the segment.

Finding the Midpoint of a Segment with Given Endpoints

To find the midpoint of a segment with given endpoints ${(0, -4)}$ and ${(9, 10)}$ , we can use the midpoint formula.

Step 1: Identify the Endpoints

The given endpoints are ${(0, -4)}$ and ${(9, 10)}$ .

Step 2: Apply the Midpoint Formula

We will apply the midpoint formula to find the midpoint of the segment.

${(x_m, y_m) = \left(\frac{0 + 9}{2}, \frac{-4 + 10}{2}\right)}$

Step 3: Simplify the Expression

We will simplify the expression to find the midpoint.

${(x_m, y_m) = \left(\frac{9}{2}, \frac{6}{2}\right)}$

${(x_m, y_m) = \left(\frac{9}{2}, 3\right)}$
