Answer :

from the question, we now that y is 12 when x is 1.2

in order to find out the constant of variation for this relation, we just need to substitute it to :

y = k x

12 = k 1.2

k = 12/1.2

k = 10

hope this helps

The constant of variation for the relation given that y is 12 when x is 1.2 is 10

How to determine the constant

From the question given above,

y ∝ x

y = Kx

Divide both side by x

K = y / x

K => Variation constant

But

  • y = 12
  • x = 1.2

Thus,

The conctant, K can be obtained as follow

K = y / x

K = 12 / 1.2

K = 10
