If the point `(a ,a)` is placed in between the lines `|x+y|=4,` then find the values of `adot`

A

|a| =2

B

|a| =1

C

`|a| lt 1 `

D

`|a| lt (1)/(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
The equation of the lines are x + y = 2 and x + y = -2 . If the point (a , a) falls between these two lines , then (a + a - 2) (a + a + 2) `lt 0`
