Question

find the ratio in which the line segment joining A (1 .5 ) and B _ (4_5) is divided by the x axis​

Answer 1

Answer:

x¹= 1

x²=4

y¹= 5

y²=5

Step-by-step explanation:

Let P divide line segment in the ratio m:n

coordinate of P ( x,0)

$y \: coordinate \: of \: p = \frac{my2 + ny1}{m + n}$

$= > 0 = \frac{5m + 5n}{m + n}$

$= > 0 = 5m + 5n$

$= > - 5m = - 5n$

$= > \frac{ - 5}{ - 5} = \frac{n}{m}$

$= > \frac{1}{1} = \frac{m}{n}$

Hence the line segment is divided in the ratio 1:1
