1.) If the focus of the parabola is (A, D), and the directrix of the parabola is y=-3/5x - 7, find the equation of the axis of symmetry in the form y=mx + k, (where m and k are in the simplest form).

2.) Let 4(x)= 8(x)^2 - 2(x) + 8, find the following in the simplest form:

A) 4(x) - 4(t)/(x - t)

B) 4(x + k) - 4(x)/k
