Step-by-step explanation:
<u><em>Verify each case</em></u>
Part 1) The graph show two identical lines, then the system has infinitely many solutions
Part 2) The graph show two perpendicular lines.
Remember that the solution of the system is the intersection point both graphs
The intersection point is (2,6)
therefore
The system has one solution at (2,6)
Part 3) The graph show two intersecting lines at (-6,-2)
Remember that the solution of the system is the intersection point both graphs
The intersection point is (-6,-2)
therefore
The system has one solution at (-6,-2)
