Study Notes

Linear Equations

In a linear equation, the coefficients are the constants that multiply the variables (unknowns).

Solutions of Linear Equations

A linear equation with one variable has exactly one solution if the coefficient of the variable is non-zero.
The solutions of a linear equation in two variables are related to the Euclidean plane, where they can be represented as points on a line.
The solutions of a linear equation in two variables form a line in the Euclidean plane.

Geometric Representation

A linear equation with two variables represents a line in the Euclidean plane geometrically.
The form of a linear equation with two variables in the Euclidean plane is ax + by = c, where a, b, and c are constants, and x and y are variables.

Multiple Variables

The form of a linear equation with multiple variables is a1x1 + a2x2 + … + anxn = c, where a1, a2, …, an, and c are constants, and x1, x2, …, xn are variables.

Implicit Assumption

When referring to a linear equation implicitly, the implicit assumption is that the equation is in the form of ax + by = c, or a1x1 + a2x2 + … + anxn = c, where the variables are multiplied by non-zero coefficients.
