- points x and y lie on cordinate axises

- the line CD is disected into 3 parts by x and y equally (trisected is the term?)

- we are given the value of C to find the possible cordinates of D

Can someone lead me in the right direction, I'm not exactly looking for answers here.

(this is for saturday school math, no idea how to, ty, im in grade 9 btw)
