sad, did not finish module C (missed out 3/4 of my essay) and my belonging essay (missed out on my 2nd related part). ._.
Bad time management is bad :l
oh i got it xD
x=2 so let PA be (2,y)
y=-5 so let PB be (x,-5)
|PB|=3/4|PA|
PB=y-(-5)
=y+5
PA=x-2
y+5=3/4(x-2)
4y+20=3x-6
3x-4y-26=0
PB=-(y+5)
PA=x-2
-y-5=3/4(x-2)
-4y-20=3x-6
3x+4y+14=0
Thanks for the help :D
