Egypt's capital is best known for preserving the last of the Seven Wonders of the Ancient World, but the city contains infinite treasures beyond the Pyramids of Giza.

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:
Some of the most common problems that are already happening are pretty much the same that'll happen in the future.
Ozone depletion
Climate change
Global warming
Acid rain
Carbon dioxide contributes to air pollution in its role in the greenhouse effect. Carbon dioxide traps radiation at ground level, creating ground-level ozone. This atmospheric layer prevents the earth from cooling at night. One result is a warming of ocean waters
