Question

the point of intersection of the lines xy+y^2-y-2x-2y+2=0 is (a,b) then a=b?
????..............................

Answer 1

Answer:

To know the point of intersection in a pair of straight lines we need to partially differentiate once w. r. t. x and then once with respect to y and solve them to get the point. For first line, 

1)⇒2x−2=0⇒x=1

2)⇒−2y+2=0⇒y=1 

Point (1,1)

For second line 

1)⇒4x−5y+1=0

2)⇒−5x+4y+1=0

On solving this, Point≡(1,1)

Hence they have the same point (1,1)

Hence distance =0
