Answer:
2n - 4.
Step-by-step explanation:
(n+8) + (n−12)
= n + 8 + n - 12
= n + n + 8 - 12
= 2n - 4.
Answer
Slope(m) = -1
Step by step explanation
Slope (m) = (y2 - y1)/(x2 - x1)
Here p1 = (-2, 3) and p2 (1, 0)
x1 = -2, y1 = 3, x2 = 1, y2 = 0
Now plug in the values in the slope formula, we get
m = (0 - 3) / (1 - (-2))
m = -3/(1 + 2)
m = -3/3
m = -1
Therefore, slope = -1
