Question

Determine wheather each equation represents a direct variatation. If it does, find the costant of variation.
2x+3y=0
someone help me please?

Answer 1

solve for y, what do you get?

Answer 2

like do 3divided by 0??

Answer 3

no, you first subtract 2x from both sides

Answer 4

then you divide both sides by 3

Answer 5

you get 3 because 2- 3 =1
1devided by 3 = 3

Answer 6

2x+3y=0

3y=0-2x

3y = -2x

y = -2/3x

Answer 7

the equation is now in the form y = kx where k = -2/3

Answer 8

i see

Answer 9

so that means that this is an equation of direct variation

Answer 10

ohh okay i get it now
