There are two ways: Implement an equation class which does what ever you want
and construct it from your function.
If you can live with a function instead of an equation try:
def line_two_points(a,b):
m = (b[1]-a[1])/(b[0]-a[0])
return lambda x: m*x +(a[1]-m*a[0])
sage: f = line_two_points((0,0),(1,1))
sage: f(2)
2
Some stuff you may want to look up:

* http://docs.python.org/ref/lambdas.html

Have fun,
