Question Analysis
This question tests the student's ability to solve a system of linear and quadratic equations graphically. The student needs to find the intersection points of the parabola and the line.

Key Concept Explanation
The key concept here is that the solutions to the system of equations are the coordinates where the parabola and the line intersect. The number of solutions corresponds to the number of intersection points.

Step-by-step Solution
1. Plot the parabola (opens downwards; the vertex can be calculated by the formula
