Neither.
Parallel lines have the same slope.
Perpendicular lines have negative reciprocal slopes.
Rewriting the 2nd equation to solve for y,
You get:
Y=1/5x + 1/2
The first equation slope is negative, and the second is positive. However, the second slope is 1/5, and not 5/1 - which would be the negative reciprocal of (-1/5)from the first equation.
Hope that helps!
Answer:
10.7 m
Step-by-step explanation:
Given that,
The speed of a sound wave, v = 6,420 m/s
The frequency of the wave, f = 600 Hz
We need to find the wavelength of the wave. We can find it using the below relation as follows :

So, the wavelength of the sound wave is equal to 10.7 m.
