    2. Which of the following pairs of coordinates are on a line with an undefined shape?
    a. (2,3) (9,8)
    b. (3,1) (4,1)
    c. (2,3) (2,10)
    C?

  2. 2. Undefined shape? That is not a math term, did you mean undefined slope? then c.

    27 is A, however, that is very provincial thinking. I would burn a text if it said that. Honestly, I would not use that text in teaching, if it is that basal, it would be of no use later.

    1. The domain of x? It is not restricted by that equation.
