Answer:
y = -2x + 10
Step-by-step explanation:
The equation is y = mx + b
1. Find the slope first.
--> (y2 - y1) / (x2 - x1) = slope
--> (-12 - -6) / (11 - 8) = (-6) / (3) = -2
2. Then, find the y-intercept (b) by plugging one of the points
--> y = -2x + b
--> -6 = -2(8) + b
--> -6 = -16 + b
--> b = 10
3. Combine
--> y = -2x + 10

Sound intensity: <span> 7.6 × 10-4 watts/m2?
To solve this problem you have to understand the threshold of hearing (Level)
</span><span>Io = 10^−12 W/m²
</span>
Solve the problem:
<span>"LI = 10×log (I / Io) dB = 10×log (7.6×10^−4 / 10^−12) dB"
</span>
and the answer is 88.81dB
