Question

Please help.

Are the graphs of the lines in the pair parallel? Explain.
y = 5x + 6
–18x + 3y = –54

A. No, since the slopes are different.

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

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

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

Answer 1

\[\to -18x+3y=-54\,\, (:3) \to -6x+y=-18 \to y=6x-18\] Do you see?
