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

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, …

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.

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 …

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.

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

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 …

We've seen linear and exponential functions, and now we're ready for quadratic functions. We'll explore how these functions and the parabolas they produce can be used to solve real-world problems.
