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

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.

Both graphs show the change in position of an object over a period of time and are similar to each other. However, the term "displacement" highlights the object's overall change in position from …

And so to check whether any material obeys Ohm's law, all you do is draw a graph of voltage versus current, and just check whether that graph is a straight line.

Let's see what we can do. Well, that looks pretty good, actually, all right, so we put our line, and our line is pretty close to passing through our points, so the points fall on our straight line, so …

Learn how to graph two-variable linear inequalities like y≤4x+3. Created by Sal Khan and CK-12 Foundation.

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

I want to plot displacement, final velocity, and acceleration, all of those as functions of time. Just so we really understand what's happening as the ball is going up and then down.

Graphs of linear equations in two variables Learn Identifying equations of linear graphs Graphing a linear equation: 5x+2y=20 Graphing a linear equation: y=2x+7

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 …
