Answer:
n = 14
Step-by-step explanation:
7n +9 = -1+6(n+4)
Distribute
7n+9 = -1 +6n+24
Combine like terms
7n +9 = 6n +23
Subtract 6n from each side
7n -6n+9 = 6n-6n +23
n+9 = 23
Subtract 9 from each side
n+9-9=23-9
n = 14
The equation of the straight line is y = -1/6(x - 10) + 4
<h3>How to determine the line equation?</h3>
The equation is given as:
y = 2x + 6
Linear equations are represented as:
y = mx + c
Where:
Slope = m
So, we have:
m = 6
The slopes of perpendicular lines are represented as:
n = -1/m
So, we have:
n = -1/6
The equation is then represented as:
y = n(x - x1) + y1
This gives
y = -1/6(x - 10) + 4
Hence, the equation of the straight line is y = -1/6(x - 10) + 4

Answer:
B
Step-by-step explanation:
The study doesn't prove a causation, only a correlation. So we can conclude that cities with good air quality do not have traffic jams.
