Question

Answer this with explanation other wise it will be very bad for you ( In case of spam)​

Answer 1

Step-by-step explanation:

Let the line segment joining the points (1, 2) and (− 2, 1) be divided by the line 3x + 4y = 7 in the ratio m:n.

Then, the coordinates of this point will be

( - 2m + n \m + n), ( m+ 2n/m+n)

that lie on the line 3x + 4y = 7

3×(-2m+n/ m +n) + 4×(m+2n/m+n)= 7

⇒ - 2 + 11 n = 7 m + 7 n

⇒ - 9 m = - 4 n

⇒ m: n = 4 : 9

waise kya aap 10 Mai ho yaani board student???

if yes so iam too so I can do any questions of maths

bye the way thanks
