Explanation:
The graph shows a ine crossing the parabola. The solution of the systems is the point where both system of equations intersect.
The line crosses the parabola at two point:
At x = 2, y = 2
This point is applicable to both. Since both have same values at this point, (2, 2) is one of the solution
At x = -2, y = -6
Both graphs have this point . This shows point (-2, -6) is also a solution
Hence, the solutions of the systems are (2, 2) and (-2, -6)
