# Is y=5x an inverse variation?

Jun 5, 2015

$y = 5 x$
here color(red) (y and x are variables and color(blue)(5 is the constant

Let us assume values for color(red)(x and observe how the values of $x \mathmr{and} y$ vary with respect to each other:

• $\textcolor{red}{x = 1} , y = \textcolor{b l u e}{5} .1 = 5$
• $\textcolor{red}{x = 2} , y = \textcolor{b l u e}{5} .2 = 10$
• $\textcolor{red}{x = 3} , y = \textcolor{b l u e}{5} .3 = 15$

It can be observed that as color(red)(x increases in value , so does color(red)(y and hence the variation is not inverse, it is direct variation.
