Answer:
its location as the center of international land trade
Explanation:
The Ottoman Empire had established on an excellent strategic position, right where all the land routes for trade between Asia and Europe were going through. That put the Ottomans in a position where they control the trade between the two continents, they imposed taxation, and that brought them a great power and wealth. That was also the reason why the Europeans started to look for alternative solutions for trade by using the seas and oceans, which eventually led to the discovery of the New World by accident.
They got some land from the Louisiana Purchase and other land they got from Mexico through the 1848 Treaty of Guadalupe Hidalgo.
You should always use a reference point such as (0,0) to determine which side of the line to shade. For example we have the equation y>2x-1 we then use the point (0,0) by substituting the point in the equation.
y>2x-1 -----> 0>2*0-1
we then solve and make sure the point satisfies the inequality.
0>2*0-1 ------> 0-1=-1 ----> 0>-1
We see that the point does satisfy the equation so we shade whatever side of the line that includes the point (0,0)
Hope this helps!
