при y = 3:
$\frac{y - 1}{4} = \frac{3 - 1}{4} = \frac{2}{4} = \frac{1}{2}$
 
при y = 1:
$\frac{y - 1}{4} = \frac{1 - 1}{4} = \frac{0}{4} = 0$
 
при y = −5:
$\frac{y - 1}{4} = \frac{-5 - 1}{4} = \frac{-6}{4} = -\frac{3}{2} = -1,5$
 
при $y = \frac{1}{2}$:
$\frac{y - 1}{4} = \frac{\frac{1}{2} - 1}{4} = \frac{-\frac{1}{2}}{4} = -\frac{1}{2} * \frac{1}{4} = -\frac{1}{8}$
 
при y = −1,6:
$\frac{y - 1}{4} = \frac{-1,6 - 1}{4} = \frac{-2,6}{4} = -\frac{26}{40} = -\frac{13}{20}$
 
при y = 100:
$\frac{y - 1}{4} = \frac{100 - 1}{4} = \frac{99}{4} = 24\frac{3}{4}$
