Distance Formula

The distance formula calculates the straight-line (Euclidean) distance between two points (x₁, y₁) and (x₂, y₂) in a two-dimensional Cartesian coordinate system:

Euclidean Distance Formula

$$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$$

This formula is derived directly from the Pythagorean theorem. When you connect two points, you form a right triangle where:

The horizontal leg has length |x₂ - x₁|
The vertical leg has length |y₂ - y₁|
The hypotenuse (distance) is what we are calculating

Additional Calculations

Midpoint Formula

The midpoint is the point exactly halfway between two points:

Midpoint Formula

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

Slope Formula

The slope measures the steepness of the line connecting two points:

Slope Formula

$$m = \frac{y_2 - y_1}{x_2 - x_1}$$

Line Equation

Using point-slope form, we can derive the equation of the line passing through both points:

Slope-Intercept Form

$$y = mx + b$$

Frequently Asked Questions

What is the distance formula between two points?

The distance formula calculates the Euclidean distance between two points (x₁, y₁) and (x₂, y₂) in a 2D plane: d = sqrt((x₂ - x₁)² + (y₂ - y₁)²). This formula is derived from the Pythagorean theorem.

How do I find the midpoint between two points?

The midpoint is calculated by averaging the x-coordinates and y-coordinates separately: Midpoint = ((x₁ + x₂)/2, (y₁ + y₂)/2). This gives you the point exactly halfway between the two original points.

What is the slope between two points?

The slope (m) measures the steepness of the line connecting two points: m = (y₂ - y₁)/(x₂ - x₁). A positive slope means the line rises from left to right, a negative slope means it falls, and a slope of zero indicates a horizontal line.

Can I calculate distance with negative coordinates?

Yes, the distance formula works with any real numbers, including negative coordinates. The squaring operation ensures the distance is always positive.

What if the two points have the same x-coordinate?

When x₁ = x₂, you have a vertical line. The slope is undefined (division by zero), and the distance simply equals |y₂ - y₁|.
