Answer 1

Answer:

A class 10 Mathematics logical question from ‘Coordinate Geometry’

Here is your answer

Step-by-step explanation:

there are Furtur moe concepts to Solve this:

1:BY GRAPHICALLY:

The lines intersect at (5,3). (You can easily establish this graphically, or you can use the 2-point formula for the line AB and then solve the pair of equations algebraically.) The ratio is then 2:3. (delta x = 2 and 3; delta y = 4 and 6

2: CONCEPTUALLY:

The lines intersect at (5,3). (You can easily establish this graphically, or you can use the 2-point formula for the line AB and then solve the pair of equations algebraically.) The ratio is then 2:3. (delta x = 2 and 3; delta y = 4 and 6

Let the ratio be k:1

We are given A (3,-1) B(8,9) are the points forming the line

By Section formula,

If P is the point of division then

P (8k-3) /k+1,(9k+1)/k+1

Are the Co ordinates of P

Since AB is intersected by x-y-2=0 at P

P is also on that line

By replacing the values of Co ordinates of P in the equation we get

k=2:3

SO k:1=2:3
