Question

Which lines are parallel to each other? Which lines are perpendicular to each other?

(a)y = x/3 + 2

(b)y = 3x - 6

(c)y = -2x + 2

(d)y = -3x - 2

(e)2y + 4x = -10

(f)y - 3x = 6

Answer 1

Hint: get each equation in y = mx+b form and look for equations that have equal slopes (m)

Answer 2

that's to find parallel equations

Answer 3

parallel to each other: b & f, c & e since slopes are the same
perpendicular to each other: a & d, since slopes are (-1/slope) of the other
