Find the variation constant and an equation of variation where Y varies directly as X and Y=60 when X=10
y=equation of variation
Still do not understand..please..
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
So, now we know that y=6x
