Quadrilateral PQRS

PQRS is a quadrilateral with P(4,4), S(8,8), and R(12,8). If vector PQ=4*vector SR, find the coordinates of Q. Solve it

Correct answer:

x =  20
y =  4

Step-by-step explanation:

P=(4,4) S=(8,8) R=(12,8)  PQ=4 SR Q=(x,y)  xPx=4 (RxSx) x4=4 (128)  x=20  x=120=20  x=20
yPy=4 (RySy) y4=4 (88)  y=4  y=14=4  y=4
