Locus of Points Practice Problems Online

Given $A=(5,0)$ and $B=(0,4)$ , what is the equation of the locus of points $P$ such that $\lvert \overline{PA} \rvert^2- \lvert \overline{PB} \rvert^2=9?$

Given $A=(9,-1)$ and $B=(-9,5)$ , what is the equation of the locus of points $P$ such that $\lvert \overline{AP} \rvert: \lvert \overline{BP} \rvert=1:2 ,$ where $\lvert \overline{AP} \rvert$ denotes the length of $\overline{AP}?$

(x-15)^2+(y+3)^2=160

(x-12)^2+(y+4)^2=160

(x-15)^2+(y+3)^2=40

(x-12)^2+(y+3)^2=80
