Incorrect. Two lines are parallel if they have the same slope. Remember, in the slope intercept form of the line, $\displaystyle{y}={m}{x}+{b}\usepackage{cmbright}\Huge\$ , the slope is the value of $\displaystyle{m}\usepackage{cmbright}\Huge\$ . What is the slope of the line $\displaystyle{y}=-{5}{x}-{8}\usepackage{cmbright}\Huge\$ ?
