System A Line 1: \( y=\frac{5}{2} x+3 \) Line \( 2: y=\frac{5}{2} x-3 \) The system has exactly one solution. Solution: \( \square, \square) \) The system has infinitely many solutions. The system has no solution.

Step 1 ：Set the expressions of \(y\) equal to each other to find the \(x\)-coordinate: \( \frac{5}{2}x + 3 = \frac{5}{2}x - 3\)

Step 2 ：Subtract \( \frac{5}{2}x \) from both sides to get: \( 3 = -3 \)

Step 3 ：Since the equation is false, there's no solution to the system.
