Question

xy = -12 What is the constant of variation for this relationship?

a. -1.2
b. -12
c. -1/4
d. -0.12

Answer 1

equation for direct variation is y = kx
and for inverse variation is = y = k/x
now in the equation what variable r u missing

Answer 2

x

Answer 3

both equation have 3 variable
x
y
and k
x and y Valeria are on left side

Answer 4

\[\large\rm y =\frac{ k }{ x }\]
if you solve this for k you should have x y = k
now what is k in that equation ?

Answer 5

-12 ?

Answer 6

yes right

Answer 7

so there is y = x/-12

Answer 8

or y = x/12 ?
