Question 326931
<font face="Garamond" size="+2">


The slope of one of the lines is -1 and the slope of the other is 1, hence the two lines are NOT parallel and must intersect in a single point somewhere.  Note that both lines have a *[tex \Large y]-intercept of 3.  They both intercept the *[tex \Large y]-axis in the same point.  Well, if the two lines intersect in only one point and they both intersect the *[tex \Large y]-axis in the same point, the *[tex \Large y]-intercept has to be the place.  Point of intersection and the single element of the solution set is *[tex \Large (0,3)]
