Question

suppose that y varies directly with x and y=12 when x=-2. what is when x=-6?

Answer 1

Y=4

How?
When they say directly you should multiply the x and y together. You would get -24, now using that number divide -24 by the new x(-6) you would get 4.

Answer 2

Answer:

Step-by-step explanation:

Y varies directly with x

First find the value of the proportionality constant K

Y=KX

Where K is d constant of proportionality

12= -2K

Divide 12 by the coefficient of K

K=12÷(-2)=-6

When X=-6, substitute the value of K

Y=KX

Y=-6×(-6)

Y=36
