Question

ans. of above question​

Answer 1

Answer:

We know that,G={x1+x2+X3 /3;y1+y2+y3/3}

as they given two points and G=(-4,-7)

(-4,-7)={-14+3+X3/3,-19+5+y3/3}

(-4,-7)={-11+X3/3,-14+y3/3}

-4=-11+X3/3

-12=-11+X3

X3=-1,

-7=-14+y3/3

-21=-14+y3

y3=-7

Therefore the third point will be C(-1,-7)
