Write an equation in slope-intercept form of the line perpendicular to y = 3x + 4 that passes through the point (3, 4).
a. y = 3x - 5b)y = 3x + 5c)y = 1/3x + 5d)y = -1/3x + 5

Hello:
the equation is : y = ax+b
the slope is a : a×(3) = -1( perpendicular to a line with a slope of   3)            because :    y=3x+4      3 is the slope    )     

a = -1/3         y=(-1/3)x+b
the line that passes through (3, 4) :4 = (-1/3)(3)+b
b =5
 the equation is :  y  = (-1/3)x+5

i think it is
