Line
A line is a contiguous sequence of text characters ending at a line boundary or the end of a text stream.
How Computers Make Books
A line is a continuous one-dimensional geometric or visual form extending between or through points.
- How it is used
- Builds page marks, shapes, and letter forms from coordinates and pixels.
- How deep it goes
- Works through endpoint definition and slope-based raster approximation, while deferring comprehensive drawing algorithms.
- Examples
- Uses endpoint pairs, shallow and steep grid lines, gray edge pixels, coordinate drawings, and letter C.
- What you can do after
- Practice/perform line approximation by selecting grid pixels and drawing coordinate-connected paths.

A line is a sequence of text characters ending at a line boundary or the end of a text stream.
- How it is used
- Processes files and standard input as sequences of lines for counting, lookup, searching, and text transformation.
- How deep it goes
- Explains line-by-line iteration, counting, inspection, and preservation, without descending into text-stream internals.
- Examples
- Uses wc-style counts, Gashlycrumb letter lookups, and Southern-style transformations of poetry lines.
- What you can do after
- Builds Python programs that read, count, search, index, and transform text one line at a time.

Geometry for Programmers
A line is a straight one-dimensional geometric object extending without curvature.
- How it is used
- Deploys lines as coordinate-based primitives for applied geometry, programming, geometric modeling, and constant-speed trajectories.
- How deep it goes
- Explains explicit, implicit, canonical, and three-dimensional representations, then applies parametric lines to motion without deriving algorithms in code.
- Examples
- Uses y = 0.5x + 1, vertical lines x = c, plane intersections, and a game character following line-and-arc trajectories.
- What you can do after
- Apply explicit, implicit, canonical, and parametric line descriptions to 2D geometry, 3D intersections, and constant-speed motion.
