**Number of Solutions**

**Determined Graphically Graph each linear system, either by hand or using a graphing device. Use the graph to determine whether the system has one solution, no solution, or infinitely many solutions. If there is exactly one solution, use the graph to find it.**

**$\left\{\begin{array}{l}-x+\frac{1}{2}y=-5\\ 2x-y=10\end{array}\right.$**

Hence, the system of linear equations has **infinitely many solutions** and the sketch of the graph is**.**** **

We are given the system of linear equations that is-

$\left\{\begin{array}{l}-x+\frac{1}{2}y=-5\\ 2x-y=10\end{array}\right.$

The system of linear equations is the collection of one or more linear equations involving the same set of variables.

We need to use the graph to determine whether the system has one solution, no solution, or infinitely many solutions.

By the process of the system of equations, we will calculate the result.

Two lines indicated correspond to the two equations from the system of linear equations.

As is evident by the graphs, the two lines are overlapping and each point on either of the lines can be considered an intersection.

So, We can conclude that the system of linear equations has infinitely many solutions.

We sketch the graph,
