Question

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

Answer 1

Answer:

y=10x

because 12y:1.2x

Answer 2

Answer:

k = 10

Step-by-step explanation:

Direct variation is, when y = kx ⇔ k = $\frac{y}{x}$

If y = 12 and x = 1.2 , then

k = $\frac{12}{1.2}$ = 10
