The equations are in standard form, and you can read the expressions for slopes for each equation.

Those slopes: -a%2F2 and b%2F3

The lines being PERPENDICULAR require the slopes to produce a product of -1.

%28-a%2F2%29%28b%2F3%29=-1
%28-a%29%28b%29=-6
highlight_green%28ab=6%29

a and b cannot finally be determined until you have more information. YOU have two equations and eight variables.
