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

Options

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`

Answer

A

Explanation

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`
