Graphs can be used to represent real life scenarios.
The true statements are:
- (b) as the altitude increases, the atmospheric pressure increases.
- (c) the atmospheric pressure is 14lb/in2 at sea level.
From the question, we can see that:
As the x values increases, the y values increases.
This means that:
As the altitude increases, the atmospheric pressure increases.
Also, when x = 0. the value of y is 14
This means that:
The atmospheric pressure is 14lb/in2 at sea level.
Hence, the true statements are: (b) and (c)
