Question

Which of the following are parallel to

y = 3x – 2
(Choose all that apply)


y = 5 – 3x

Y= 3x

y = 3x – 1

y = 3x – 4

y = -3x

Answer 1

y=3x-1,y=3x-4

Explanation:

y=mx+c

where is gradient, parallel lines have same gradient

y=5-3x

=-3x+5

m=-3

y=-3x

m=-3

y=3x-1

m=3 ,the gradient is equal to the original equation

y=3x-4

m=3,the gradient also equal to the given equation

Answer 2

y = 3x
y = 3x - 1
y = 3x - 4

i’m pretty sure in order for lines to be parallel, they have to have the same slope but different y- intercepts
