What’s a Linear Equation? An Equation with a Straight Line Story

A linear equation is a mathematical statement that embodies the simple yet powerful concept of a straight line. It is written in the form y = mx + c, where y is a variable representing the vertical axis or ordinate, x is a variable representing the horizontal axis or abscissa, m is a constant known as the slope or gradient, and c is a constant known as the y-intercept or displacement.

Types of Linear Equations: A Classification into Four Forms

Linear equations come in various forms, each with its own distinct characteristics. Standard form is the most common form, represented as y = mx + c, where the slope and y-intercept are explicitly defined. Slope-intercept form separates the slope and y-intercept, using y = mx + b format. Point-slope form emphasizes a specific point on the line and the slope, written as y – y1 = m(x – x1). Intercept form highlights the y-intercept and slope, expressed as y = c + mx.

Solving Linear Equations: Choose Your Weapon

To effectively solve linear equations, we have an arsenal of powerful techniques at our disposal. Substitution involves solving for one variable in one equation and substituting its expression into the other equation. Elimination employs the sum-or-difference method to combine or eliminate variables, revealing a solvable equation. Graphing provides a visual representation of the equation, allowing for solutions to be easily identified.
