Linear equations and graphs come up all the time in mathematics, science, engineering, and business. They're one of the foundational skills for understanding algebra and more advanced math courses.

Part of the beauty of linear equations is that we can write them in different (but equivalent!) ways to highlight different features. Whether we want a particular point, an intercept, or the slope of the line …

In this video, we explore the idea of linear relationships using everyday examples. We start with students A and B to show how marks and effort can be compared.

Use the power of algebra to understand and interpret points and lines (something we typically do in geometry). Topics you'll explore include the slope and the equation of a line.

When distances, prices, or any other quantity in our world changes at a constant rate, we can use linear functions to model them. Let's learn how different representations, including graphs and equations, …

When we learned to solve linear inequalities, we learned that multiple values can satisfy an inequality. How do we graph the infinite number of (x, y) values that can satisfy a linear inequality?

Linear equations like y = 2x + 7 are called "linear" because they make a straight line when we graph them. These tutorials introduce you to linear relationships, their graphs, and functions.

A linear and quadratic system can be represented by a line and a parabola in the x y -plane. Each intersection of the line and the parabola represents a solution to the system.
