(Section 0.14: Lines) 0.14.11 Example 2 (Finding Intercepts) Find the x - and y -intercepts of the line 2 x ± y = ± 4 . § Solution Find the x -intercept. We substitute y = 0 and solve for x . 2 x ± y = ± 4 ² 2 x ± 0 () = ± 4 x = ± 2 The x -intercept is ± 2 , or the point ± 2,0 () . Find the y -intercept. We substitute x = 0 and solve for y . 2 x ± y = ± 4 ² 20 () ± y = ± 4 y = 4 The y -intercept is 4, or the point
