Correct. The y-intercept of the line is (0, -4), so the equation looks like $\displaystyle{y}={m}{x}-{4}\usepackage{cmbright}\Huge\$ , where m is the slope of the line. The points (0, -4) and (1, -2) are on the line, so the slope is 2, and therefore the equation is $\displaystyle{y}={2}{x}-{4}\usepackage{cmbright}\Huge\$ .
