The slope if the given line is $\frac {2}{3}$ , so the line perpendicular line has slope $\frac {-3}{2}$ .

so flip the numerator and denom and add negative sign?

so inthis case the equation will be $y = \frac{-3}{2}x + 14$

Yes. The slope of the perpendicular line is the negative reciprocal of the given slope.
