Introduction

In mathematics, the X-Y coordinate system is a fundamental concept used to represent points and locations in a two-dimensional space. It is a crucial tool in various fields, including geometry, trigonometry, and engineering. In this article, we will delve into the world of X-Y coordinates, exploring their definition, properties, and applications.

What are X-Y Coordinates?

X-Y coordinates are a way to describe the position of a point in a two-dimensional plane. The X-axis represents the horizontal direction, while the Y-axis represents the vertical direction. Each point in the plane is assigned a unique pair of coordinates, (x, y), where x is the horizontal distance from the origin and y is the vertical distance.

The X-Y Coordinate Plane

The X-Y coordinate plane is a rectangular grid that consists of a horizontal X-axis and a vertical Y-axis. The origin, (0, 0), is the point where the X-axis and Y-axis intersect. The X-axis is usually labeled with positive and negative values, while the Y-axis is also labeled with positive and negative values.

Properties of X-Y Coordinates

X-Y coordinates have several important properties that make them useful in mathematics and engineering. Some of these properties include:

Distance: The distance between two points (x1, y1) and (x2, y2) can be calculated using the distance formula: d = √((x2 - x1)^2 + (y2 - y1)^2)
Midpoint: The midpoint of two points (x1, y1) and (x2, y2) can be calculated using the midpoint formula: (x, y) = ((x1 + x2)/2, (y1 + y2)/2)
Slope: The slope of a line passing through two points (x1, y1) and (x2, y2) can be calculated using the slope formula: m = (y2 - y1)/(x2 - x1)
