Step-by-step explanation:
The coordinates of the intersection of the line are the solution of the system of equations.

The system of equations has no solution. Therefore, the lines are parallel (the intersection does not exist).
This is the graph for the equation, it crosses through points (0,-8) (-2,4) (-1.6,0) and its vertex is (-2,2)
