Determine an equation of a perpendicular line but with the same y intercept

Open bracket

A linear equation is represented with:

Where


By comparison:


So, the slope of
is m
Because the new line is perpendicular to
, the relationship between their slopes is:

Where
slope of the first equation
slope of the second equation
Substitute m for
in 

Hence, the slope of the new equation is: 
From the question, we understand that they have the same y intercept.
So, the equation of the new equation is:

Answer:
It is difficult to cross.
Explanation:
The Sahara desert is a vast region about the size of the continental United States that is extremely dry and barren. The lack of water resources in the desert make the land unsuitable for agriculture and human population.
As a result, the Sahara acts as a giant natural wall both economically, culturally, and socially since relations between states to the north and south of the desert are difficult.
