Correct. The y-intercept of the line is (0, 1), so the equation looks like $\displaystyle{y}={m}{x}+{1}\usepackage{cmbright}\Huge\$ , where m is the slope of the line. The points (0, 1) and (1, 3) are on the line, so the slope is 2, and therefore the equation is $\displaystyle{y}={2}{x}+{1}\usepackage{cmbright}\Huge\$ .
