Interpreting linear functions and equations Learn which form is most appropriate for different uses.

Take an overview of the three main forms of linear equations: slope-intercept, point-slope, and standard. Summary: Forms of two-variable linear equations For example, write the equation of the line that passes through the points (0,1) and (5,4).

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. Learn how to graph linear equations that are given in 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. 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. Learn about slope (the steepness of a line) and how to find it. Learn about intercepts and practice finding them from graphs, tables, and equations. Practice plugging in values for variables to see whether or not an equation is true. Understand what a solution to an equation really means.
