Question

Let y varies directly as x; If y = 24 when x = 8, then the linear equation is _____________

Answer 1

Answer:

Y is directly proportional to x,

y = Kx

----( where K is the constant )

------------------------------------

1.Putting y=12 & x=4 ; we get

12 = k×4

k = 12/4

k = 3

=======================

2. x=5 ; y=?

y = Kx

= 3×5

y = 15
