If P( x,y) is any point on the line joining the point A(a,0) and B( 0,b) then show that x/ a+ y/b=1

If P( x,y) is any point on the line joining the point A(a,0) and B( 0,

1.	If P( x,y) is any point on the line joining the point A(a,0) and B( 0,b) then show that x/ a+ y/b=1
Answer» Any other method Midpoint point of a and ba+0/2 , b+0/2 = x , ya+0=2xx/a=1/2. (1)b+o=2y. (2)y/b=1/2From 1 and 2x/a +y/b= 1/2+1/2x/a +y/b=1
