Work Step by Step

3x+2y=5 2y=-3x+5 y=$\frac{-3x+5}{2}$ y=$\frac{-3x}{2}$+$\frac{5}{2}$ y=-$\frac{3}{2}$x+$\frac{5}{2}$, slope is -$\frac{3}{2}$ line is perpendicular, slope is $\frac{2}{3}$ through (-2;-3) y=mx+b -3=$\frac{2}{3}$(-2)+b -3=-$\frac{4}{3}$+b -3+$\frac{4}{3}$=b -$\frac{9}{3}$+$\frac{4}{3}$=b -$\frac{5}{3}$=b y=mx+b y=$\frac{2}{3}$x-$\frac{5}{3}$
