Which equation is a direct variation function? y = x y = 1/4 x + 2 y = x2 , y = 4,

Soloha48 [4]

Answer:

$y=x$ and $y=\frac{1}{4}x$

Step-by-step explanation:

We know,

'Direct Variation function' is the function where two quantities vary directly i.e. variables x and y are said to be directly varying if 'y=kx' where k is the constant of variation.

Thus, from the options, we see that the function,

$y=x$ is varying directly with the constant of variation i.e. k = 1.

$y=\frac{1}{4}x$ is also varying directly with constant $k=\frac{1}{4}$
