Question

Where do I plot 5/2 on a line? And how do I plot 5/2 on a 7inch line segment?

Answer 1

Answer:

Coordinates of P=(K+1K

(−4)+1(3),

K+1K(8)+1(−5))

⇒(K+1−4K+3,K+18K−5)

It is given that, P lies on the line x+y=0.

Therefore,

(K+1−4K+3+K+18K−5)=0

⇒K+1−4K+3+8K−5=0

⇒4K−2=0

⇒4K=2

⇒K=21

So, the value of K is 21.
