The browser used for posting questions on this site is rubbish. It is quite useless for mathematics since it strips out most symbols so that we cannot tell what the question is meant to be. We could try to guess but in some cases that is not possible and then we may as well make up our own questions and answer them!
In this case we cannot see an equation, only an expression. And an expression cannot have a solution.
If you mean: 2y = -4x-12 then y = -2x-6 and -6 is the y intercept
2y - 4x = -12 Algebraically rearrange to 2y = 4x - 12 Divide both sides by '2' y = 2x - 6 So at the 'y' intercept, x = 0 Substituting x = 0 We have y = 2(0) - 6 Anything multiplied '0' is equal; to '0' Hence y = 0 - 6 y = -6 is the value of the y-intercept.
Without an equality sign the given expression can't be considered to be a straight line equation
4x+2y = 6 2y = -4x+6 y = -2x+3 Perpendicular slope is 1/2
It simplifies to: -4x-12
4x-2y = 12 -2y = -4x+12 y = 2x-6 Therefore the y intercept is -6 and the slope is 2
4x+2y = 12 2y = -4x+12 y = -2x+6 So the y intercept is 6 and the slope is -2
2y-4x=-12 Add 4x to each side 2y=4x-12 Divide each side by 2 y=2x-6 The y-intercept is (0,-6)
The y-intercept of the graph of 4x + 2y =12 is probably 6
If you mean: 2y = -4x-12 then y = -2x-6 and -6 is the y intercept
No because without an equality sign the given expression can't be considered to be an equation.

If: 2y-4x = -12 Then: y = 2x-6 So the y intercept is -6 and the slope is 2
-6
If the two equations are (i) 4x + 2y = 12 and (ii) x + 2y = 6, proceed as follows: Rewrite (ii) as x = 6 - 2y; substitute this expression for x into (i) to result in 4(6 - 2y) + 2y = 12, or 24 - 8 y + 2y = 12, or - 6 y = 12 -24 = -12, or y = -12/-6 = 2. Then, back to (ii) again, x = 6 - 2(2) = 2.
