Let’s get started.

What Is a Midpoint?

In coordinate geometry, the midpoint is the exact middle point between two coordinates on a plane. If you connect two points with a straight line segment, the midpoint divides that segment into two equal parts.

If the two points are: $(x₁, y₁) \text{ and } (x₂, y₂)$ (x1,y1) and (x2,y2)

The midpoint formula is: $M = \left(\frac{x₁ + x₂}{2}, \frac{y₁ + y₂}{2}\right)$ M=(2×1+x2,2y1+y2)

This formula averages the x-coordinates and y-coordinates separately.

Example Calculation

Let’s understand how the tool works with a practical example.

Example:

Point 1: (2, 4)
Point 2: (6, 8)

Midpoint Calculation:

$M = \left(\frac{2 + 6}{2}, \frac{4 + 8}{2}\right)$ M=(22+6,24+8) $M = (4, 6)$ M=(4,6)

Distance Formula:

$d = \sqrt{(x₂ – x₁)^2 + (y₂ – y₁)^2}$ d=(x2−x1)2+(y2−y1)2 $d = \sqrt{(6 – 2)^2 + (8 – 4)^2}$ d=(6−2)2+(8−4)2 $d = \sqrt{16 + 16} = \sqrt{32} = 5.6569$ d=16+16=32=5.6569

Slope Formula:

$m = \frac{y₂ – y₁}{x₂ – x₁}$ m=x2−x1y2−y1 $m = \frac{8 – 4}{6 – 2} = 1$ m=6−28−4=1

The calculator automatically performs all these steps and displays the results instantly.

Understanding Distance Between Two Points

The distance formula calculates the length of the line segment between two coordinates. $d = \sqrt{(x₂ – x₁)^2 + (y₂ – y₁)^2}$ d=(x2−x1)2+(y2−y1)2

This formula is derived from the Pythagorean theorem and is widely used in geometry, physics, engineering, and computer graphics.

Understanding Slope

The slope measures the steepness of a line. $m = \frac{y₂ – y₁}{x₂ – x₁}$ m=x2−x1y2−y1

If slope > 0 → Line rises from left to right
If slope < 0 → Line falls from left to right
If slope = 0 → Horizontal line
If x₂ = x₁ → Vertical line (slope undefined)

Our calculator automatically detects vertical lines and displays:
“Undefined (vertical line)”

Frequently Asked Questions (FAQs)

1. What is a midpoint in math?

A midpoint is the exact middle point between two coordinates on a graph.

2. What is the midpoint formula?

M = ((x₁ + x₂)/2, (y₁ + y₂)/2)

3. How do you calculate distance between two points?

Using the formula: √[(x₂ − x₁)² + (y₂ − y₁)²]

4. How do you find slope?

Slope = (y₂ − y₁) / (x₂ − x₁)
