Can someone answer this Algebra question asap? thanks

Answer 1

y = - 24

Explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 12 when x = - 3

k =
`(y)/(x)` =
`(12)/(-3)` = - 4

y = - 4x ← equation of variation

When x = 6, then

y = - 4 × 6 = - 24
