It might be let me think a square root is right
Answer:

Explanation:
Given

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:

It would be perennial grasses and legumes. :)
Answer:
subduction zone
Explanation:
subduction zones—that is, locations where a lithospheric plate bearing oceanic crust slides down into the upper mantle under the force of gravity.
