Which of the following could be the equation of a line parallel to the line 3x + 2y = 8?

(A) $$y =\frac{2}{3}x + 7$$
(B) $$y =\frac{-2}{3}x + 7$$
(C) $$y =\frac{3}{2}x + 7$$
(D) $$y =\frac{-3}{2}x + 7$$
(E) $$y =\frac{3}{2}x - 7$$

Parallel lines have identical slopes.

Rewrite the given line equation into point-slope form:
$$3x + 2y = 8$$
$$2y = -3x + 8$$
$$y = -\frac{3}{2}x + 4$$

From the answer choices, the only line equation that has a slope identical slope to that in the question is $$y =\frac{-3}{2}x + 7$$ -- that is,
