Correct. The line shown has slope -1 (since it contains the points (0, 4) and (1, 3)) and its y-intercept is (0, 4), so the equation of the line is $\displaystyle\+{y}={\left(-{1}\right)}{x}+{4}\usepackage{cmbright}\Huge\$ , which is the same as $\displaystyle{y}=-{x}+{4}\usepackage{cmbright}\Huge\$ .
