Linear equations & graphs: Unit test About this unit Let's explore different ways to find and visualize slopes and intercepts, and how these concepts can help us solve real-world problems.

Test your understanding of Linear equations, functions, & graphs with these 22 questions.

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 …

Then we introduce the concept of independent and dependent variables, and use graphs like data usage vs. cost and fan speed vs. cooling effect to explain what makes a relationship linear. …

They are a bunch of ways to graph linear equations. What we'll do in this video is the most basic way. Where we will just plot a bunch of values and then connect the dots.
