Incorrect. Two lines are parallel if they have the same slope. By first expressing the line in slope intercept form, we can determine its slope. If $\displaystyle{x}+{2}{y}={4}\usepackage{cmbright}\Huge\$ , then $\displaystyle{2}{y}=-{x}+{4}\usepackage{cmbright}\Huge\$ . Does this help you figure out the slope?
