## A List of Lessons in the Linear Equations Curriculum

## What Is a Linear Equation?

A linear equation is an equation with two variables (**x**and

**y**). It shows a straight line when plotted on a graph. Here is an example of a linear equation:

Here is this linear equation plotted on a graph:

## Linear Equation Curriculum

All the lessons on this page are related to linear equations. They are grouped into mini-curriculums (or*curricula*if you prefer the Latin plural) to help you organise your learning. A brief description is given for each mini-curriculum. Click the

## We Have Widgets!

Many of our lessons feature widgets like the one below. This widget lets you create your own graph and download it as an image, which – if you're a tutor – you might find useful for creating worksheets.## Equations and Linear Equations

Equations show that two mathematical expressions are equal to each other. Linear equations are the simplest type of equation and show straight lines when plotted. In this mini-curriculum, you will learn about equations and linear equations.

## Lines, Slope and Y-Intercept

Linear equations can be written in different forms. The slope-intercept form of a linear equation lets us read off what the slope and y-intercept of a line are. In this mini-curriculum, you will learn what the slope and y-intercept of a line are and how you can read them off from a linear equation.

## Slope-Point Form

Linear equations can be written in different forms. The slope-point form of a linear equation lets us read off what the slope of a line is and the Cartesian coordinates of a point the line passes through. In this mini-curriculum, you will learn about the slope-point form of a linear equation.

## General Form

Linear equations can be written in different forms. The general form of a linear equation does not let us read off anything about the line it represents. In this mini-curriculum, you will learn about the general form of a linear equation.

## Equation of a Line Between Two Points

If we know the Cartesian coordinates of two points on a line, the equation of the line can be found. In this mini-curriculum, you will learn about how to find the linear equation of a line between two points.
