- 4.7 Graphing Lines Using Slope- Intercept Form Identify Parallel Lines EXAMPLE 3 Identify Parallel Lines Which of the following lines are parallel? Line a: -x + 2y = 6line b: -x + 2y = -2line c: x + 2y = 4 3 Compare the slopes. Lines a and b are parallel because each has a slope of . Line c is not parallel to either of the other two lines because it has a slope of - .
