Question

Find an equation of variation in which Y varies as X and the following is true Y=40 and X=38

Answer 1

y = kx
y/x = k k is called the constant of variation

Now putting in the values you get:

40/38 = k

or

20/19 = k This is reduced to its lowest fraction from the above

Answer 2

thanks but thats incorrect

Answer 3

Sorry, but maybe I don't quite understand the question since I know that y=kx is an equation involving the constant of variation.
