Work Step by Step

Using the properties of equality, the given equation is equivalent to \begin{array}{l}\require{cancel} \dfrac{1}{2}y=1 \\\\ 2\cdot\dfrac{1}{2}y=2\cdot1 \\\\ y=2 .\end{array} The graph of lines of the form $y=b,$ where $b$ is a constant, is a horizontal line passing through $(0,b).$ Hence, the graph of the equation above is a horizontal line passing through $(0,2).$
