Practice Relating linear contexts to graph features Get 5 of 7 questions to level up!

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 …

This topic covers: - Intercepts of linear equations/functions - Slope of linear equations/functions - Slope-intercept, point-slope, & standard forms - Graphing linear equations/functions - Writing …

Graphs of linear equations and functions questions deal with linear equations and functions and their graphs in the x y -plane. For example, the graph of y = 2 x 1 is shown below.

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.

Zachary, One way to say it is that: A linear function is an equation that's solution set of (x,y) pairs when graphed would create a line on the graph.

Learn how to create a graph of the linear equation y = 2x + 7. Created by Sal Khan and CK-12 Foundation.

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 …

Learn about a class of equations in two variables that's called "linear equations." They are called that way because their graph is a line. These are the most basic and probably most useful …

This powerful concept blends numerical precision with graphical clarity, illuminating the behavior of the line on the graph in a way that is both straightforward and captivating!
