No. If you will transform both to the form y = mx + b, we should see whether they are equal or not.
x + y = -1 ---> y = -x - 1
2x + 3y = -4 ---> y = -(2/3)x - 4/3
Since both m, and b are different, then the 2 are definitely different from each other.

If (x + y = -1) is true, > -2(x + y = -1) is true. > -2x - 2y = 2 is true
- 2x - 2y = 2
2x + 3y = -4 add
____________
0 + y = -2
x + y = - 1 (When y = -2) > x -2 = - 1 > x = 1
So x+ y = -1 is the same as 2x +3y = - 4
Only when x = 1 and y = -2
Check:
1 - 2 = -1 > - 1 = -1 right
2 - 6 = -4 > - 4 = -4 right

No.
cuz in eq. 1 if u multiply it with anything the coefficients of x , y and the constant value will be equal

Since the second equation is not a multiple of the first equation, they are not "the same".

No, there is no linear dependency between the two equations.

No, if you put x as -0.5 and y as -0.5 you don't get the right answer for the second equation.

It could be.
It all depends on the values you put for x and y.
