Overview

The Cartesian System of Coordinates is a powerful mathematical tool that connects algebra and geometry. It allows us to represent geometric shapes and positions using algebraic equations. By drawing two perpendicular number lines — the x-axis and y-axis — we create a coordinate plane where every poi

Key Concepts

The Cartesian plane consists of two

The Cartesian plane consists of two perpendicular number lines: the horizontal x-axis and the vertical y-axis, intersecting at the origin (0, 0). Any

The distance between two points P(x₁

The distance between two points P(x₁, y₁) and Q(x₂, y₂) is given by √[(x₂−x₁)² + (y₂−y₁)²]. This formula is derived using the Pythagorean theorem by c

If a point R divides

If a point R divides the line segment joining P(x₁, y₁) and Q(x₂, y₂) in the ratio m:n, then the coordinates of R are: - Internal division: ((mx₂ + nx

The area of a triangle

The area of a triangle with vertices A(x₁, y₁), B(x₂, y₂), C(x₃, y₃) is: ½ |x₁(y₂−y₃) + x₂(y₃−y₁) + x₃(y₁−y₂)| This can also be written as a determina

The slope (m) of a line

The slope (m) of a line is the tangent of the angle (θ) it makes with the positive x-axis: m = tanθ. For two points (x₁, y₁) and (x₂, y₂), slope m = (
