Choose the best description of it's solution. if the system has exactly one solution, give it's solution."

Answer:
No Solution
Explanation:
Given the system of equations:
[tex]\begin{array}{c}\text{ Line 1: }y=-\frac{1}{2}x+1 \\ \text{ Line }2\colon y=-\frac{1}{2}x-3\end{array}[/tex]From the graph, we see that the two equations form parallel lines. This means that they will never intersect.
Therefore, the system has NO SOLUTION.
