The constant of variation is the number that relates two variables that are directly proportional or inversely proportional to one another. Watch this tutorial to see how to find the constant of variation for a direct variation equation. Take a look!
The constant of variation is the number that relates two variables that are directly proportional or inversely proportional to one another. But why is it called the constant of variation? This tutorial answers that question, so take a look!
Looking for some practice with direct variation? Watch this tutorial, and get that practice! This tutorial shows you how to take given information and turn it into a direct variation equation. Then, see how to use that equation to find the value of one of the variables.
Wondering if a point is part of the equation of a line? Got the equation of the line but no graph? No problem! Just take that point and plug it into the equation and simplify. If you end up with a true statement, the point is indeed part of the equation. If you end up with a false statement, then that point is not part of the equation. See this process first-hand in this tutorial!
