Form a differential equation representing the given family of curves by eliminating arbitrary constants a and b.`x/a+y/b=1`

Explanation

Given, `(x)/(a)+(y)/(b)=1`……………..`(1)`
`implies (1)/(a)+(1)/(b)(dy)/(dx)=0`
`implies0+(1)/(b)(d^(2)y)/(dx^(2))=0=y'=0`
which is the requred differerntial equation.
