Virtual Nerd: Use the Formula for Inverse Variation to Write an Equation

Circles aren't functions, so how is it possible to write the equation for a circle? Pupils first develop the equation of a circle through application of the Pythagorean Theorem. The lesson then provides an exercise set for learners to...

In this overview video of direct and inverse variation, Sal shows the general form of each equation and its differences. The listener gains an intuitive understanding of the differences by highlighting how the x and y values vary with...

Sometimes, it is not always obvious which equations are direct variations and which are inverse variations. In this video, five different equations are considered. Each is manipulated and rewritten to determine whether there is a direct...

Apply rational functions to a problem-solving situation through inverse variation. The video tutorial explains the concept of inverse variation and introduces learners to the formula. The instructor explains how to solve problems that...

Inverse, reverse, indirect, what? Indirect variation, indirect proportion, constant of variation, inverse proportion, inverse variation, oh my!! Just watch the video and the instructor will explain these things rather straightforward.

Use the formula for direct variation to solve for y, after finding the value of k. When you use the formula and determine the value of k and x, you can plug in those values to determine the value of y. A quick tutorial that takes you...

Enhance pupil understanding of proportions and variable relationships by studying direct and inverse variation. Use the idea of a proportional relationship to teach direct variation. Then use a similar pattern to help individuals...

Given a table of x and y values, is it possible to write a linear equation from this information? There will be several steps involved. First is to use the point-slope formula to find a slope. Then use that slope and one of the ordered...

In this tutorial, discover how to use the formula for direct variation to find the constant of variation and then solve for your answer. [2 :12]

Don't panic! There is a pretty simple straightforward formula to solve this problem. Some of the words are a bit overwhelming: indirect variation, inverse, constant of variation, indirect proportionality. But one simple formula and just...
