Find the coordinates of the points which divide the line segment joining the points (-4,0) and (0,6) in four equal parts
Answers
Let C , D and E are placed between A and B .
e.g., A____C____D_____E_____B
Here , AC = CD = DE = EB
So, C divides the line AB into 1 : 3 ratio
here A≡(-4 , 0) and B ≡(0,6)
Now, C ≡ [ (1 × 0 + 3 × -4)/(1 + 3) , (1 × 6 + 3 × 0)/(1 + 3)]
C≡(-3 , 3/2 )
Similarly , E divides the line AB into 3 : 1 ratio.
So, E ≡ [ (3 × 0 + 1 × -4)/(3 + 1) , (3 × 6 + 1 × 0)/(3 + 1)]
E ≡ (-1 , 9/2)
And D is the midpoint of AB
so, D ≡ [(-4 + 0)/2 , (0 + 6)/2 ]
D ≡ ( -2 , 3)
