Answer:

y intercept is -2

Explanation:

y intercept is when x is 0.

original equation:

If you want to make it into something solvable, you want to move everything but y to one side.

1. x+4y+8=0

2. 4y+8=-x

3. 4y=-x-8

4. y=-1/4x-2

5. Since this is a linear function, all you have to do to find the y intercept is plug x in with 0. (mentioned above)

6. y=-1/4(0)-2

7.y=-2

8. y int=-2
