## Elementary and Intermediate Algebra: Concepts & Applications (6th Edition)

Using the properties of equality, the given equation is equivalent to \begin{array}{l}\require{cancel} -5x=10 \\\\ x=\dfrac{10}{-5} \\\\ x=-2 .\end{array} The graph of lines of the form $x=a,$ is a vertical line passing through $(a,0).$ Hence, the graph of the equation above is a vertical line passing through $(-2,0).$
