#-2/3=10/9x+y#

#m(x-x_1)=y-y_1#

We find the slope using this formula:

#m=(x_2-x_1)/(y_2-y_1)#

#=>m=(-4-6)/(3-(-6))#

#=>m=-10/9#

We let #x_1=-6# and #y_1=6#

#=>-10/9(x-(-6))=y-6#

#=>-10/9(x+6)=y-6#

#=>-10/9x-20/3=y-6#

#=>-10/9x-2/3=y#

#=>-2/3=y+10/9x#

#=>-2/3=10/9x+y#

We see that #A=10/9#, #B=1#, and #C=-2/3#
