Would it be.... \[(3\sqrt{2}-\sqrt{10})x-(\sqrt{10}+\sqrt{2})y-2\sqrt{10}-\sqrt{2}=0\]

Alright this is new to me but this is what It says to do \[3x-y=1\] \[x+y=-2\] \[(3+1)x+(1-1)y=-2+1\] \[4x=-1\] \[x=\frac{-1}{4}\] to make sure this is correct test for each for y \[3(\frac{-1}{4})-y=1\] \[\frac{-3}{4}-1=y\] \[\frac{-7}{4}=y \] \[\frac{-1}{4}+y=-2\] \[\frac{7}{4}=-y\] \[\frac{-7}{4}=y\]

intersection point is \[[-.25,-1.75]\] which is a point on your bisector line also next find the slopes and take the arimetic mean line 1 \[3x-1=y\] \[m=3\] \[x+y=-2\] \[-x-2=y\] \[-1=m\] \[\frac{-1+3}{2}=1\] using that withhin the point slope equation \[y-y_1=m(x-x_1)\] \[y-(-1.75)=1(x-(-.25))\] \[y+1.75=1x+.25\] \[y=1x-1.5=x-1.5\]
