Step-by-step explanation:
ANSWER
Given, A(−1,3),B(4,2),C(3,−2)
(i) Co-ordinates of centroid G is
G(x,y)=(
2
(x
1
+x
3
)
,
(y
+y
=(
(−1+4+3)
(3+2−2)
6
)=(2,1)
Hence, the co-ordinates of the centroid G of the triangle is (2,1)
(ii) Slope of AC=
−x
−y
=
(3−(−1))
(−2−3)
4
−5
So, the slope of the line parallel to AC is also
Now, the equation of line through G is
y−1=(
)(x−2)
4y−4=−5x+10
5x+4y=14
Thus, the required line equation 5x+4y=14.
but sorry brother it's not my phone it's my father's phone ......
