def _(n=slider(-5,20,step_size=1),b=slider(1,20,step_size=1),auto_update=False):
    f= n*x+b
    pt=plot(n*x+b,(x,-2,10))
    dot= point((0,b),pointsize=80,rgbcolor=(1,0,0))

Hello,

Python is very strict about indentation (but not about whether you should use space or tab though)

This is good

x = 3
def my_function():
    s = "my x is %s" % x
    print s

These are bad

x = 3
  def my_function():
    s = "my x is %s" % x
    print s

(the f is indented but should not)

x = 3
def my_function():
      s = "my x is %s" % x
    print s

(the indentations are different in the two lines)
