Question

Which equation represents a proportional relationship? a. y = 3 x b.y=−3 x+2 c.y=2(x+13) d.y=12 x help ill give brainliest
plz help

Answer 1

Answer:

a and d

Step-by-step explanation:

A proportional relationship has the form

y = kx ← k is the constant of proportionality

y = 3x ← is in this form with k = 3 → a

y = 12x ← is in this form with k = 12 → d

Answer 2

Good evening ,

Step-by-step explanation:

a. y = 3 x  represents a proportional relationship because y/x =3 (constant)

d. y=12 x represents a proportional relationship because y/x = 12 (constant).
