If the points A(x,y) , B(a,0) and C(0,b) are collinear ,prove that x/a

1.	If the points A(x,y) , B(a,0) and C(0,b) are collinear ,prove that x/a + y/b = 1
Answer» The area of triangle ABC=01/2(x(0-b)+a(b-y) +0(y-0))=00r -bx+ ab-ay +0=0bx +by=abboth side divide by abbx/ab + by/ab = ab/abx/a +y/b=1\xa0\xa0 Subscribe jaroor karna yarr plz Subscribe Royal fun unlimited on YouTube
