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

y = 6x + 9
27x – 3y = –81

a.  Yes, since the slopes are the same and the y-intercepts are the same.

b.  No, since the slopes are different.

c.  No, since the y-intercepts are different.

d.  Yes, since the slopes are the same and the y-intercepts are different.

y = 6x + 9----------slope is 6
27x – 3y = –81----------3y=27x+81-------y=9x+27---------slope is 9

b.  No, since the slopes are different.
