compare the slopes and tell whether the lines are parallel.
y = x + 2 and y = x 3
can you tell me how to set up the problem so that I can do it.

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.
