Inverse of the function 2x-6y=1
 To get the inverse of the function, first, interchanged the variables such x will be y and y will be x.
 (1)  2y – 6x = 1
 Then, find the value of y in the new equation,
 (2)  2y – 6x + 6x = 1 + 6x
 2y = 1 + 6x
 (3) (1/2)(2y) = (1 + 6x)(1/2)
  y = (1 + 6x) / 2
 The reverse of the function is y = (1 + 6x)/2.
