A
So, first we look at the equations 
y= (x+3)^2+4 changes to 
y= (x+1)^2+ 6
So, the first one is saying that we start at (-3,4)
(since when in the parentheses, it's opposite) and the second one is saying start at (-1,6), so it moved on the x-axis 2 units to the right and on the y-axis, it moved 2 units up

The solution of the given system of equation is x = -3 and y = 4 respectively.       
<h3>What is a system of linear equations?</h3>
A system of linear equations can be defined as a number of equations needed to solve the equations. For n number of variables n number of equations are required.
The given system of equations is as,
y = 4x + 16                   (1)
y = −2x − 2                  (2)
In order to solve them, substitute equation (2) into (1) as follows,
 4x + 16 = −2x − 2
=> 4x + 2x = -2 - 16
=> 6x = -18
=> x  = -3
Then, y = -2 × -3 - 2 = 4
Hence, the solution of the given system of equation is x = -3 and y = 4.
