Answer:
D
Step-by-step explanation:
First, find the coordinates of pointD if A(2,-6), B(10,2) and point D divides line segment AB in the ratio of 5:3.
If point D divides the segment AB in the ratio m:n, then
![D\left(\dfrac{nx_A+mx_B}{m+n},\dfrac{ny_A+my_B}{m+n}\right)](https://tex.z-dn.net/?f=D%5Cleft%28%5Cdfrac%7Bnx_A%2Bmx_B%7D%7Bm%2Bn%7D%2C%5Cdfrac%7Bny_A%2Bmy_B%7D%7Bm%2Bn%7D%5Cright%29)
So
![D\left(\dfrac{3\cdot 2+5\cdot 10}{5+3},\dfrac{3\cdot (-6)+5\cdot 2B}{5+3}\right)=D(7,-1)](https://tex.z-dn.net/?f=D%5Cleft%28%5Cdfrac%7B3%5Ccdot%202%2B5%5Ccdot%2010%7D%7B5%2B3%7D%2C%5Cdfrac%7B3%5Ccdot%20%28-6%29%2B5%5Ccdot%202B%7D%7B5%2B3%7D%5Cright%29%3DD%287%2C-1%29)
Point C has the x-coordinate the same as point A and the y-coordinate the same as point D.
Thus, C(2,-1)
