Question

(17) Find the ratio in which the point (2,y) divides the line segment joining the points Al-2,-
2) and
B(3,7). And the value of y.​

Answer 1

Answer:

the ratio of AB line divided by p is 4:1

and value of y is 26/5 or 5.2

Answer 2

Answer: ratio 4:1 and y = 6

Step-by-step explanation:

LET THE RATIO BE m:n

2={3m+(-2n)}/(m+n)

or, 2m+2n=3m-2n

or, 2m-3m=-2n-2n

or, -m=-4n

or, m/n=4/1

∴, m:n=4:1

∴, y=(my₂+ny₁)/(m+n)

or, y=(4.7+1.2)/(4+1)

or, y=(28+2)/5

or, y=30/5

or, y=6

∴, the required ratio is 4:1 and y=6.
