Incorrect. The equation has the form $\displaystyle{y}={m}{x}+{b}\usepackage{cmbright}\Huge\$ . The coefficient of x is the slope, m, of the line. So the line has a slope of $\displaystyle-{2}\usepackage{cmbright}\Huge\$ . The constant $\displaystyle-{4}\usepackage{cmbright}\Huge\$ tells you that the y-intercept is $\displaystyle{\left({0},-{4}\right)}\usepackage{cmbright}\Huge\$ . The correct answer is $\displaystyle-{2}\usepackage{cmbright}\Huge\$ .
