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 math courses. Plus, they can be really useful for modeling real-world situations and solving problems.

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 relationship is any relationship between two variables that creates a line when graphed in the x y ‍ -plane. Linear relationships are very common in everyday life.

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.

Identify features of linear graphs from their equations; Write linear equations based on graphical features; Determine the equations of parallel and perpendicular lines

What is the slope of the graph of the given equation? Your answer should be a simplified proper fraction, like 3/5, or a simplified improper fraction, like 7/4 Show calculator

In this unit, we learn about linear equations and how we can use their graphs to solve problems. Skip to main content If you're seeing this message, it means we're having trouble loading external resources on our website.

Whether we want a particular point, an intercept, or the slope of the line to be most prominent, there's an equation form that shows it off. Part of the beauty of linear equations is that we can write them in different (but equivalent!) ways to highlight different features.
