To find the value of s, we can use the slope formula:

m = (y2 - y1) / (x2 - x1)

Given:
- Point (-4, s)
- Point (-3, -4)
- Slope m = -3

Substituting the given points and slope into the formula:

-3 = (-4 - s) / (-3 - (-4))

-3 = (-4 - s) / 1

-3 = -4 - s

Now, let's solve for s:

Add 4 to both sides:

-3 + 4 = -4 - s + 4

1 = -s

Divide both sides by -1:

-1 = s

Therefore, the value of s is -1.
