One-Step Inequality with multiplication and division example
Sal expounds on the concept of solving and graphing one-step inequalities. He solves a two practice problems along the way. If shown in conjunction with Khan's other inequality video lesson, they would make a great lesson on inequalities.

What Does the Constant 'k' do in y = |x|+k?
How do you translate absolute value equations vertically? What's a parent equation? What is a constant k in an equation? How does the value of the constant k change the graph of the equation vertically? So many questions. Watch as the...

What's Negative Correlation?
If the y-value decreases as the x-value increases then you have a negative correlation. Meaning that the line-of-fit has a negative slope.

What's Positive Correlation?
If the y-value increases as the x-value increases then you have a positive correlation. Meaning that the line-of-fit has a positive slope.

What's a Function?
There are many ways to represent a function. The main idea though is that for every input there is an output. Watch this video as the instructor illustrates and explains several different ways to show a function. She demonstrates domain...

Slope Intercept Formula
If you are a line then you can be written in slope-intercept form. Have students view this video to understand what slope-intercept does, how it works and why the y is so important. This video is very explicit and clear.

Testing if a Relationship is a Function
This short video looks at different points on a coordinate plane and answers a question about whether these points could represent a function. The answer is determined by looking at each point individually to determine whether given a...

What's the Formula for Slope?
Slope? Does that mean the angle of the line on the graph? Yes, but it's not referred to as an angle on the graph. The slope of the line means how much does the line move up or down in comparison as to how much it moves left or right. So,...
