Hi
*[tex \LARGE\ Using \ the \ standard \ slope-intercept \ form \ for \ an \ equation \ of \ a  \ line \ y = mx + b ] 
*[tex \LARGE\ where \ m \ is \ the \ slope \ and \ b \ the \ y-intercept]
A: 3y+x=6  OR y = (-1/3)x+2    |Slope m = (-1/3)
B: y=3x+2                      |Slope m = 3/1
C: 3x+y=0  OR y = -3x          |Slope m = -3
Line A and B represent perpendicular lines
(slopes are negative reciprocals of one another, that is (-1/3)*3/1 = -1
