Question

6. Which two lines are parallel?

I. 4y = 3x + 1
II. 4y = 3x – 1
III. 3y = 4x – 1 (1 point)
II and III
I and III
I and II
none of the above

Answer 1

parallel lines have same slope so 1 and 2 fits the description

Answer 2

Remember y=mx+c, where "m" is your slope, and "c" is your y intercept.
As @jayz657 said above, parallel lines must have a identical slopes otherwise they're not parallel. So in this case, m = 3 and that's your slope. Roman Numerals I and II both have slopes of 3 where III has a slope of 4. So the answer is "I and II"
