here is ur answer
hope this will help you
The required ratio is 3: 4
Given:
Point (4,0) divides the line segment joining points (4, 6) and (4-8)
To find:
The ratio in which the point divides the line segment
Solution:
Formula used:
P(x, y) = [ mx₂+nx₁ /(m+n), my₂+ny₁/(m+n) ]
Where, P(x, y) divides the line segment joining the points A (x₁, y₁) and B(x₂, y₂) in m: n ratio.
From the data,
Point (4,0) divides the line segment joining points (4, 6) and (4-8)
Let a: b be the ratio
By using the formula,
=> (4, 0) = [ a(4) +b(4)/(a+b), a(-8)+b(6)/(a+b) ]
=> (4, 0) = [ 4a + 4b/(a+b), -8a +6b /(a+b) ]
=> -8a +6b /(a+b) = 0
=> -8a +6b = 0
=> 8a = 6b
=> a/b = 6/8
=> a/b = 3/4
Therefore,
The required ratio is 3: 4
