Answer:
y = -16
Step-by-step explanation:
Given that,
y varies directly with x. Mathematically, we can write it as follows :

or

Where
k is constant
Put y = 12 and x = -3 to find k. So,

Now put k = -4 and x = 4. So,

So, the required value of y is equal to -16.

Answer:
A
Step-by-step explanation:
Plug in the values of each of the coordinate pairs into the linear system.
2x - 8y = 0, -3x - 8y = 20
A)
2*-4 - 8*-1 = 0
- 8 - (-8) = 0 -> CORRECT!
-3x - 8y = 20
-3*-4 - 8*-1 = 20
12 - (-8) = 20 -> CORRECT!
You don't need to try any other pairs, you already know that this is the solution to the problem! Remember, in the future, just plug all the coordinate pairs into the equation. Whichever one makes the equation true is the correct solution! Hope this helps!
