I Cant graph this one..i'm tired just take a review of my work
ratio of x  then.. Point (x,y)=(x.,0);

P1(-5,4); P2(4,-8);

assume M(x,0);
by distance formula( P1M)^2=(P2M)^;

P1M^2= (x+5)^2 +(0-4)^2;
           =x^2+10x+25 + 16;
           =x^2 +10x +41....;
P2M^2= (x-4)^2 +(0+8)^2;
           = x^2-8x+16 +64;
P1M^2=P2M^2;
x^2+10x+41=x^2-8x +80;
18x=39;
x=39/18;
x=13/6..
M(13/6,0)...
