If Y varies directly with x, and Y = 8 when x = 2, find the constant for variation K.

I am a little confussed on this on and do not know where to begin. Any help with this would be greatful. Please show me step by step how to get the solution for this equation so I can understand how to do these types of equations. Thanks


Y varies directly with x
Y α X
⇒ Y= K *X
When Y=8 and x=2
We have  8=K*2
           ⇒ K=4
