Find the variation constant and an equation of variation where Y varies directly as X and Y=60 when X=10

k=variation constant
y=equation of variation

Still do not understand..please..

• Algebra -

If y varies directly as x, it means that

y = kx

where k is called the variation constant. That is, y is always some multiple of x. It varies "directly".

So, we want to find k. To do that, we need to know both x and y. Luckily, they have said that y=60 when x=10. Plug them into the equation:

60 = k*10
k=6

So, now we know that y=6x

Aha...thank you..
