Question

prove thai the point (a,0),(0,b)and(1,-1) are colliner if 1/a+1/b=1

Answer 1

Answer:

At a = 2 and b = 2,  the equation satisfy.

Step-by-step explanation:

Given,

Point (a, 0) ,(0, b) and (1, -1)

on plotting you get a straight line  

but at a certain condition

Means it satisfy 1/a + 1/b = 1

Put value of a = 2 and b = 2

1/2 + 1/2 = 1

So on the value of a = 2 and b = 2  the equation satisfy.
