Adding to what Anand Mehta said, the negation of that statement has two interpretations.
(i) there are zero lines through that point that are parallel to the given line (this is called Elliptic or Reimannian Geometry)
(ii) there is an infinite number of lines that pass through the point and parallel to a given line (this is called Hyperbolic or Lobachevskian Geometry)
I might add that the study of non-Euclidean Geometries are absolutely fascinating.

How did Thomas Edison invent the phonograph?
This was a tin foil phonograph. The phonograph played cylinders and not disks which led to his discovery that he could playback messages via this invention.
Why was Robert hooke's discovery so important?
His discovery led to this improvement in science. He studied a dead cork [cell] and saw that it had many similar compartments that looked like holding cells, therefore the name Cells came to be. Robert Hooke saw the compartments with a special microscope that he built and invented. This microscope, however, was no where near as strong as the microscopes that we have today in our modern day technological lives.This is pretty much all that I can think of off of the top of my head, so BYE!!!

Alpha particles led to what discovery of what?
discovery of the atom's structure
How did the discovery of electrons make it necessary to change one of Dalton's postulates?
The discovery of electrons showed that atoms were not indivisible as Dalton had proposed, but instead contained subatomic particles. This led to a revision of Dalton's postulate that atoms were the smallest, indivisible particles, as it became clear that atoms could be divided into even smaller components such as electrons.
