In theory, hydrogen has infinitely many spectral lines. The "Balmer series" has four lines in the visible spectrum; additional lines are in the ultraviolet. Other "series" have other lines - it seems that all of them are either in the ultraviolet or infrared. For more information, read the Wikipedia article on "Hydrogen spectrum". The reason there are four VISIBLE lines is basically chance - an excited hydrogen atom emits light at certain frequencies (which can be calculated, see the article for more details); our eyes see a certain range of electromagnetic waves that happens to include four of those lines.
The answer will depend on the relative positions of the points.
(-4, 3) is a single point. An infinite number of lines, all with different slopes, can contain it.
Slanting lines are lines that are straight but lean in another direction.
Either perpendicular lines if the lines create 90o angles or intersecting lines.
Those lines are perpendicular.Those lines are perpendicular.Those lines are perpendicular.Those lines are perpendicular.
No. In vacuum(i.e.no continuum lowering), both have an infinite number of lines in the spectrum, hence the question makes no sense.
it means it just diesnt
Just one line for hydrogen.
Rydberg
The fraunhofer (absorption) and excitation spectrum of hydrogen has lines for each energy level that electrons can pass from one excitation stat to another.

Niels Bohr studied the emission lines of Hydrogen.
The absorption lines in the infrared portion of the spectrum of a star that are produced by hydrogen are from the Balmer series. The Balmer series were discovered by Johann Balmer in 1885.

The spectral lines. Each element has a characteristic "fingerprint" in a spectrum.
