Answer 1

9514 1404 393

Answer:

  C.  Slope-intercept

Step-by-step explanation:

There are numerous forms of the equation of a line. Here are a few.

  y = mx + b . . . . slope-intercept form; slope m, y-intercept b

  y -k = m(x -h) . . . . point-slope form; point (h, k), slope m

  ax +by = c . . . . standard form; mutually prime integers, a > 0

  x/a +y/b = 1 . . . . intercept form; x-intercept a, y-intercept b

  ax +by +c = 0 . . . . general form

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1 . . . . two-point form; points (x1, y1), (x2, y2)

  (y2 -y1)/(x2 -x1) = (y -y1)/(x -x1) . . . . you might call this rise-run form

The given equation best matches slope-intercept form; slope 9, y-intercept 2.
