Y=4/5X+5
Y=4/5X-5 ARE PARALLEL LINES BECAUSE THEY HAVE THE SAME SLOPES (4/5).

Parallel lines have identical slopes. Since all of the choices are in slope intercept form, you only need to find two of the choices with equal coefficients on the x terms.

The 2nd and 3rd have the same slope so are parallel.
