The problem is already set up and can be answered by inspection.
Look at the coefficients in front of the x in each equation. There is just a + and a -, which implies one equation has +1 slope and the other a -1 sope. ("1" is never written as a coefficient - the absence of a number in front of x implies "1").
With unequal slopes, the lines are not parallel.
