put both equations in standard form
y - 3x = -5 (equation 1)
-7y + 21x = 35 (equation 2)
multiply equation 1 by 7 (this is done so either one of your variables will cancel... if both variables cancel then these lines are parallel)
7y - 21x = -35
-7y + 21x = 35
0 = 0
therefore your lines are parallel
