Question

In a direct variation equation, f(x)=6 when x = 4. What is the direct variation equation?

Answer 1

Answer:

$f(x) = \dfrac{3}{2}x$

Step-by-step explanation:

The general direct variation equation is

y = kx

Plug in x = 4 and y = 6 and solve for k.

6 = k * 4

4k = 6

k = 6/4 = 3/2

$f(x) = \dfrac{3}{2}x$

Answer 2

Answer:

1.5x
