Answer

parallel

Work Step by Step

We know that if the slopes of two lines are the same, then they are parallel. To check whether the slopes are the same, we put both equations in slope intercept form. The first equation is in slope intercept form. Rearranging the other equation gives: $y = -x +20.$ From this, we see that the two lines are parallel.
