Graphing lines and slope
Contents
Use the power of algebra to understand and interpret points and lines (something we typically do in geometry). This will include slope and the equation of a line.

Let's get cozy with the x and y axis, plotting ordered pairs, quadrants, and reflection points.
Understand what a solution to an equation really means. Practice plugging in values for variables to see whether or not an equation is true.
Learn about intercepts and practice finding them from graphs, tables, and equations.
Learn about slope (the steepness of a line) and how to find it.
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.
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.
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).
Learn how to graph two-variables linear inequalities.
