Answer:
where are the decimal numbers?
1 has the greatest value, it's worth 100,000,000 or 100 million.
It could be a linear graph with a negative slope
x axis is height above ground and y axis id air pressure
so there willbe a point at (0,14.7) on y axis representing the pressure at sea level. There will be another point at (3.6, 7.35) where air pressure is half that at ground level. The straight line will continue until it reaches the x axis ad (0, 7.2) where there is no air pressure.
The expression is
and the simplified form is
good luck
