Answer 2

Hint: a direct variation is y = kx where k is any real number

Answer 3

c?

Answer 4

that's an inverse variation equation

Answer 5

since it's in the form y = k/x

Answer 6

ohhhh so a?

Answer 7

that's a joint variation equation, notice you have 2 variables on one side

Answer 8

hmm b?

Answer 9

no lol, sounds like you're just guessing at this point?

Answer 10

choice B is another inverse variation equation, just in a different form

Answer 11

ok d lol . and i thought d wasnt it cause of its form .

Answer 12

2/3x=y

y = 2/3x

its in the form y = kx where k = 2/3

Answer 13

oh ok thank you

Answer 14

you're welcome
