  2. If all we know is the point (0,7) then it must be of the form

    y = a(x-7) * ...

    where ... is some fraction involving x-stuff.

  3. the vertical asymptote is at -2 and the horizontal asymptote is at 5

  4. so, y = 5(x-7)/(x+2)

  7. the vertical asymptote means you have (x+2) in the bottom
    the zero means you have (x-7) in the top
    The top and bottom have equal degree, so the y-asymptote is the ratio of the coefficients of the highest power of x. The fraction (x-7)/(x+2) has a horizontal asymptote at y=1. So, multiply by 5.
