This resource, developed by Khan Academy, allows students to test their math skills by answering questions concerning linear equations that are "more than abstract concepts and exercises." This problem set within the "Two-Variable Linear Equations and Introduction to Functions" section allows students to practice representations of linear equations and their x- and y-intercepts to build an intuitive understanding of how equations look and behave in graph form. Within the resource, students can receive hints on how to solve equations, watch YouTube videos that provide assistance, and use a scratch pad to sketch out their thoughts.

Khan Academy, founded in 2006, "offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom."
