Examples

## Not run: 
x <- 100
y <- 100
line <- list(m=Inf,b=2)
check_point_side_of_line(list(m=Inf,b=2),0,0)
check_point_side_of_line(list(m=Inf,b=2),2,0)
check_point_side_of_line(list(m=Inf,b=2),3,0)
check_point_side_of_line(list(m=1,b=2),0,0)
check_point_side_of_line(list(m=1,b=2),0,2)
check_point_side_of_line(list(m=1,b=2),0,3)
