The line 3y−6x+9=0 is parallel to which other line?

Question

Between this options

1. y=3−2x
2. y=x−3
3. y=2x+10
4. y=6−6x

Answer 1

it's parallel to number 3

to be parallel the lines have to have the same slope

the slope is the coefficient of the x term if the equation is solved for y

number 3 has slope 2, like the given equation's 6/3 = 2
