The answers are B, E, and F.
(3/4) : (2 1/4)p = 0
(3/4) : ((2 + 1/4))•p = 0
1.333333p = 0
p = 0
Ax + By = C
It cant be y=mx+b because that's for slope intercept and I'm in 11th grade and right now I'm passing math 4 with an 96 so you can trust me . oh and if you want add me as a friend and we can help each other and others that need the help

ANSWER: -1/4
EXPLANATION:
4x-y=9
y=4x-9
(so slope/gradient of this line is 4 as y= mx+c and the coefficient of x here is 4)
(formula for perpendicular slopes) m1 multiplied by m2 = -1, where m= gradient
So, m1 x 4= -1
m of perp line= -1/4
