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

and

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,

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

is also varying directly with constant

Two choices are correct answer.

 y = x   and y = 1/4 x

Step-by-step explanation:

We have given four equations.

We have to choose the equations that are direct variation function.

Direct variation function is defined as the relation where one variable vary constant times to the other variable.

let two variables are x and y.

y = kx   where k is constant.

Comparing given equation , we notice that

y = x is direct variation function where k = 1.

y = 1/4 x is direct variation function where k = 1/4.

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
