+Using the linear function it can be proven. Denote the segment ends with ($x_1$,$y_1$) and ($x_2$, $y_2$). The function has the following
 form: &f(x) = ax + b&. The slope of $f(x)$, in our case $a$, is $\frac{y_1-y_2}{x_1-x_2}$, so $f(x)$ becomes $f(x) = \frac{y_1-y_2}{x_1-x_2} * x + b$.
 
 This means that every points along the line has the following form: $(x, f(x))$ which has become $(x, \frac{y_1-y_2}{x_1-x_2} * x + b)$. Number $x$ can
