Question

if the points (a,0),(0,b),(1,1) are not collinear then the condition is ​

Answer 1

Step-by-step explanation:

Given that three points are collinear, (a,o),(o,b) and (1,1)

Since the points are collinear, area of triangle formed by these points is equal to O.

21[x1(y2−y3)+x2(y3−y1)+x3(y1−y2)]=021[a[b−1]+0[1−0]+1(0−b)]=0⇒ab−a−b=0⇒a+b=ab∴a1+b1=1
