y=5xy=5x
here color(red) (y and xyandx are variables and color(blue)(55 is the constant

Let us assume values for color(red)(xx and observe how the values of x and yxandy vary with respect to each other:

  • color(red)(x = 1) , y = color(blue)(5).1 = 5x=1,y=5.1=5
  • color(red)(x=2 ), y = color(blue)(5).2 = 10x=2,y=5.2=10
  • color(red)(x=3) , y = color(blue)(5).3 = 15x=3,y=5.3=15

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