Question

Find the ratio in which the line joining (-5,1) and (1,-3) divides the straight line joining the points (3,4) and (7,8).​

Answer 1

Answer:

Now, let x(1) = -5, x(2)= 1

Similarly, y(1)= 1 and y(2)= -3

and x'(1)=3 , x'(2)=7

And , y'(1)=4, y'(2)=8

Step-by-step explanation:

Now, what you basically have to do is:

(x'(2)-x'(1)²) +(y'(2)-y'(1)²)^1/2 /(x(2)-x(1)²)+(y(2)-y(1)²) ^1/2

therefore , after a bit lengthy calculation, you would get the answer, as (2×2^1/2)/13^1/2

and the rationalisation would provide you with the answer

(2×26^1/2)/13
