Answer:
The system of equations are


Equations (1) and (2) are same and these two given equations represents the same line.
Therefore the given system is consistent and it has an infinite number of solutions, and also it is dependent
Explanation:
Given system of equations is


To verify that the given system of equations have infinitely many solutions :
Equation (1) is

Equation (2) becomes


Dividing by (-2) on both sides we get

Therefore Equations (1) and (2) are same and these two given equations represents the same line.
Therefore the given system is consistent and it has an infinite number of solutions, and also it is dependent
