Incorrect. The slope of the given line is 6. A perpendicular line has a slope that is the negative reciprocal of 6, so its equation has the form: $\displaystyle{y}=-\frac{{1}}{{6}}{x}+{b}\usepackage{cmbright}\Huge\$

To find b, substitute $\displaystyle{\left(-{18},{10}\right)}\usepackage{cmbright}\Huge\$ for x and y. The correct answer is 7.
