Question

y-axis divide the line segment joining A(4, 2) and B(8, 3) in the ratio-
(a) 1:2 (b) 3:1 (c) 1:3 (d) 2:1​

Answer 1

Answer:

your answer is b . please mark me as a brainliest

Answer 2

Step-by-step explanation:

Equation of AB

$\frac{y - 2}{x - 4} = \frac{3 - 2}{8 - 4} = \frac{1}{4}$

or,

$y = \frac{1}{4} (x - 4) +2$

At y axis x=0 then the coordinate at y axis will be

$y = - 1 + 2 = 1$

That is (0,1)

Let the Ratio is K:1 .

Then

$\frac{2k - 3}{k - 1} = 1 </p><p>or, k =2$

Hence the ratio is 2:1
