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.
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 …
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. We can then graph those x-y pairs …
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 …
