  3. Linear equations and functions | 8th grade math | Khan Academy

    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, …

  4. Linear equations and functions | Khan Academy

    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.

  5. Unit 2: Graphs and forms of linear equations - Khan Academy

    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 …

  6. Graphing a linear equation: 5x+2y=20 (video) | Khan Academy

    We can graph a the linear equation like 5x + 2y = 20 by rewriting it so y is isolated, then plugging in x values to find their corresponding y-values in a table.

  7. Graphs of linear equations and functions | Lesson - Khan Academy

    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.

  8. Graphing a linear equation: y=2x+7 (video) | Khan Academy

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

  9. Graphing linear equations — Basic example - Khan Academy

    Video transcript - [Instructor] A line is graphed in the xy-plane as shown. Which of the following equations represents the line? They give us a bunch of equations here and so there is several ways …

  10. Two-variable linear equations intro (video) | Khan Academy

    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 equations you …
