Are the graphs of the lines in the pair parallel? Explain.

y = 4x + 6
–15x + 3y = –45

Yes, since the slopes are the same and the y-intercepts are the same.
Yes, since the slopes are the same and the y-intercepts are different.
No, since the y-intercepts are different.
No, since the slopes are different.
