y = x + 2 and y = -x -3

can you tell me how to set up the problem so that I can do it.

**drwls**, Tuesday, February 5, 2008 at 1:08amThe 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.
