Answer:
Slope is -3, equation is y=-3x+b, where b can be any number but not 7.
Step-by-step explanation:
Parallel lines have the same slope, so the slope of a line parallel to this is also -3.
An example of a parallel line to this is y=-3x+2, or y=-3x-4.
It looks like you're trying to solve
3x₁ + 7x₂ + s₁ = 49
x₁ +4x₂ +s₂ = 31
Fill in the given values for x₁ and s₁ and your system reduces to
7x₂ = 49
4x₂ +s₂ = 31
The first of these equations tells you x₂ = 49/7 = 7, so the second equation becomes
28 +s₂ = 31
and it is immediately obvious that s₂ = 3
Your solution is (x₁, x₂, s₁, s₂) = (0, 7, 0, 3).
