Question

Point R divides PQ in the ratio 2:3. If thr coordinates of P are (0,0) and that of R are (10,-8) then find the coordinates of Q.​

Answer 1

Answer:

50/3. -40/3

Step-by-step explanation:

P= ( 0 ,0)

Q= ( x, y)

R = (10, -8)

x=( mx1 + n x2) /m+n

y= (my1 + n y2) /m+n

10= (2x0 h 3xX )/ 5

50= 3X

X= 50/3

similarly

-8= (2x0 h 3xY )/ 5

-40= 3Y

-40/3= Y
