Answer:
The correct options are 2 and 3.
Step-by-step explanation:
In the given graph y-axis represents the atmospheric pressure, in pounds per square inch and x-axis represents altitude in miles above sea level.
From the given graph it is noticed that as altitude (value of x) increases, the atmospheric pressure (value of y) decreases and as altitude (value of x) decreases, the atmospheric pressure (value of y) increases.
At sea level, the value of x is 0.
The y-intercept of the graph is 14.
Therefore The atmospheric pressure is at sea level. Option 2 is correct.
As the altitude (value of x) approaches sea level (x=0), the atmospheric pressure increases.
Therefore the correct options are 2 and 3.
