Chapter 1: Section 1.1, Page 4

For consistency’s sake, this passage should really read:

In addition, we are specifying some arguments for how that line should be drawn, from point A (1,0) to point B (4,5). If you think of that line of code as a sentence, the function is a verb and the arguments are the objects of the sentence. Th e code sentence also ends with a semicolon instead of a period.

The correction here is that point A should be (1,0) and not (0,1) since that’s the point I started with. Same goes for Fig 1.2. There’s nothing wrong with saying (0,1) of course, it’s just not consistent with the beginning of the section.
