Step-by-step explanation:
Given [Missing from the question]

Required
Write a system of linear equations
The solutions to this question is open and have different solutions
Solving (8) (-6,-2)
Let the equations be: x + y and 2x - y

--- (1)

-- (2)
So, the equations are:
and 
Solving (9) (-12, 18)
Let the equations be: 3x - y and 4x + y




So, the equations are:
and 
Solving (9): (2,0)
Let the equations be: x + y and x - y




So, the equations are:
and 
The y-intercept is the constant in the equation: 5.
In a word problem, it might not be clear which operation the problem is asking you to do. But, 3 key words from which you know the problem is asking you to add are: increase, together, and gained. Though these are not all of them, these are some of the (arguably) most important ones.
