Find the equations of the diagonals of the square formed by the lines `x=o,y=0,x=1` and `y=1.`

A

`y=x,y+x=1`

B

`y=x,x+y=2`

C

`2y=x,y+x=(1)/(3)`

D

`y-=2x,y+2x=1`

Text Solution

Verified by Experts

The correct Answer is:
A
Equation of OB is `y-0=(1-0)/(1-0)(x-0)`
`y=x`
and equation of AC is `y-0=(1-0)/(0-1)(x-1)`
`y=x+1`
`rArrx+y-1=0`
