Question Analysis
This question tests the student's ability to find the intersection point of two linear equations graphically. The student must identify the point where the two lines cross.

Key Concept Explanation
The solution to a system of linear equations is the point where the graphs of the equations intersect. This point satisfies both equations simultaneously.

Step-by-step Solution
1. Graph the line (slope 1, y-intercept 3).
2. Graph the line (slope -1, y-intercept 1).
3. Identify the point where the two lines intersect. In this case, the intersection point is .
4. Verify the solution by substituting into both equations:
For
