Summary_Forms_of_two_variable_linear_equations

Take an overview of the three main forms of linear equations: slope-intercept, point-slope, and standard. Learn which form is most appropriate for different uses.

Graphing_slope_intercept_equations

Learn how to graph linear equations that are given in slope-intercept form. For example, graph y=2x+3.

Writing_slope_intercept_equations

Learn how to write the equation of a line (in slope-intercept form) when given the graph of the equation or two points on the line. For example, write the equation of the line that passes through the points (0,1) and (5,4).

Slope

Learn about slope (the steepness of a line) and how to find it.

Two_variable_linear_equations_intro

Understand what a solution to an equation really means. Practice plugging in values for variables to see whether or not an equation is true.

Intro_to_slope_intercept_form

Make an introduction with the most common form of linear equations, slope-intercept form! For example, y=3x+5 is a linear equation in slope-intercept form.

Horizontal_vertical_lines

You know what horizontal and vertical lines are, but how do their equations look? And what is their slope? Learn all about it in this tutorial.
