Answer:

constant of variation k = 10 when y=12 and x = 1.2

Step-by-step explanation:

We are given If y varies directly as x, and y is 12 when x is 1.2, what is the constant of variation for this relation?

y = 12

x = 1.2

Constant of variation = k = ?

We know that if y varies directly as x then:

We need to find k:

Putting values:

So, constant of variation k = 10 when y=12 and x = 1.2
