Question

Equation a: 3x y = 6 equation b: 6x - 2y = 4 equation c: y = 3x - 2 equation d: y = 1/3x 7 which two lines are perpendicular?

a. a and b
b. b and c
c. a and d
d. c and d

Answer 1

perpendicular have slopes that multil to -1
for
ax+by=c
slope=-a/b

and

y=mx+b
m=slope

equations find slope
A. -3/1=-3
B. -6/-2=3
C. 3
D. 1/3

1/3 times -3=-1

A and D



C is the answer
