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 average of two points in a coordinate plane. In this article, we will discuss how to calculate the midpoint of two points in a coordinate plane.

What is a Midpoint?

A midpoint is a point that lies exactly in the middle of a line segment. It is the point that divides the line segment into two equal parts. The midpoint formula is used to find the coordinates of the midpoint of a line segment.

Midpoint Formula

The midpoint formula is given by:

\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 coordinates of the two points.

Calculating the Midpoint of Two Points

To calculate the midpoint of two points, we need to use the midpoint formula. Let's consider two points $(4, \frac{b}{x_1})$ and $\left(\frac{8}{x_2}, \frac{2}{2}\right)$ . We need to find the midpoint of these two points.

Step 1: Identify the Coordinates of the Two Points

The coordinates of the two points are:

$(4, \frac{b}{x_1})$
$\left(\frac{8}{x_2}, \frac{2}{2}\right)$

Step 2: Apply the Midpoint Formula

To find the midpoint of the two points, we need to apply the midpoint formula:

\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 coordinates of the two points.

Step 3: Substitute the Values

Substituting the values of the coordinates of the two points, we get:

\left(\frac{4 + \frac{8}{x_2}}{2}, \frac{\frac{b}{x_1} + \frac{2}{2}}{2}\right)

Step 4: Simplify the Expression

Simplifying the expression, we get:

\left(\frac{4x_2 + 8}{2x_2}, \frac{b + 2x_1}{2x_1}\right)

Step 5: Write the Final Answer

The final answer is:

\left(\frac{4x_2 + 8}{2x_2}, \frac{b + 2x_1}{2x_1}\right)
