Question

Tell whether the equation represents direct variation. if it does, give constant variation. 2y-3x=0

Answer 1

okay first simplify it to y=kx

Answer 2

direct variation equations are in the form

y = kx

when k is the variation constant...

can you put your equation into this form

Answer 3

oooh i dont really know how to start it,

Answer 4

add 3x to both sides on the equation

Answer 5

well first add the -3x to both sides
then divide the 2 on both sides to isolate the y

Answer 6

2y=3x?

Answer 7

yes!

Answer 8

now isolate the y

Answer 9

3x/2?

Answer 10

y=3/2x

Answer 11

now is it a direct variation?

Answer 12

nooooo, .. . ?

Answer 13

why would you say that?

Answer 14

wait, no. . it is a direct because if you graph it its gonna have to rise and then run and then soon the graph would collide right?

Answer 15

yes it is direct

Answer 16

haha Thanks guys :)

Answer 17

welcome! :)
