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.
