The equation in required form is: -x+2y = 12
Step-by-step explanation:
Given equation is:

In order to convert the equation in 
Multiplying both sides by 2

subtracting x from both sides

Hence,
The equation in required form is: -x+2y = 12

Answer: -3
Step-by-step explanation:
If it is below sea level, it should be a negative number, so it is -3.
Y= 4 is perpendicular to the x- axis
The x- axis is the horizontal line, and the y- axis is the vertical line
