(1 pt) Which equations show direct variation between x and y? Choose all answers that are correct. A.3x=y B.y =4.2/x C.y/x=6 D.y=0.5x = 9

@PoetryPrincess

OpenStudy (crashonce):

direct variation means that two numbers change accordingly

OpenStudy (crashonce):

\[x \alpha y\] this is the equationof a direct variation

OpenStudy (anonymous):

that is a higher grade level than me idk what that is

OpenStudy (crashonce):

this means x=ky, where k is a constant. or y=kx, find the soln

@aahmed123

OpenStudy (anonymous):

sorry, idk :( this isnt my grade level.

OpenStudy (anonymous):

ok what grade are u

OpenStudy (anonymous):

OOH LOOK ANOTHER QUESTION GOTTA RUN CYA

OpenStudy (crashonce):

@meg11111111 this is the basic to direct variation

OpenStudy (anonymous):

can u just give the answer

Nnesha (nnesha):

equation for direct variation is \[\huge\rm y = kx\] where k is constant of variation

OpenStudy (anonymous):

can u give the answers

OpenStudy (crashonce):

we explain

Nnesha (nnesha):

solve all answer choices for y if you get y = k times x that would be your answer

OpenStudy (crashonce):

refer to nneshas formula

OpenStudy (crashonce):

theres only one answer in that format :)

OpenStudy (anonymous):

b and d

Nnesha (nnesha):

answer can be 2 or 3 or one solve all answer choices for y if you get y = number times x that would be your answer

OpenStudy (anonymous):

there can be more than one answer

OpenStudy (crashonce):

No which answer is in the form y=kx

Nnesha (nnesha):

yes that's right there can be 3 answer or all of them remember y = number times x would represent direct variation

OpenStudy (anonymous):

y=fraction with x ?

Nnesha (nnesha):

3 answer choices are already solved for y solve C) for y

Nnesha (nnesha):

yeah that could be fraction of numbers like 1/2 times x (# must multiplication of x)

OpenStudy (anonymous):

i dont want the answers to those problems read the question

Nnesha (nnesha):

you need equation in direct variation form
