Answer
(a) to D.
(b) to B.
(c) to A.
(d) to C.
Work Step by Step
(a) $y=3x+2$ has positive slope and positive y-intercept, thus (a) to D.
(b) $y=-3x+2$ has negative slope and positive y-intercept, thus (b) to B.
(c) $y=3x-2$ has positive slope and negative y-intercept, thus (c) to A.
(d) $y=-3x-2$ has negative slope and negative y-intercept, thus (d) to C.
