Incorrect. Find the slope using the given points: $\displaystyle\frac{{-{1}-{2}}}{{-{12}-{\left(-{6}\right)}}}=\frac{{-{3}}}{{-{6}}}=\frac{{1}}{{2}}\usepackage{cmbright}\Huge\$

Substitute the slope (m) into $\displaystyle{y}={m}{x}+{b}\usepackage{cmbright}\Huge\$ . Substitute either point for x and y in the equation and solve for b. This is the y-intercept. The correct answer is 5.
