#### Work Step by Step

Using $y=mx+b$ where $m$ is the slope, the slope of the first equation, \begin{array}{l}\require{cancel} 2x+y=3 \\\\ y=-2x+3 \end{array} is $m_1= -2 .$ Using $y=mx+b$ where $m$ is the slope, the slope of the second equation, \begin{array}{l}\require{cancel} y=4-2x \\\\ y=-2x+4 \end{array} is $m_2= -2 .$ Since $m_1=m_2,$ then the given lines are $\text{ parallel .}$
