The general type linear equation: Ax + By + C = 0 Where A, B are not simultaneously 0 The slope of the line-A / B (B = 0 without gradient) The general linear form equation can be expressed in any linear coordinate planes. When the equation Ax + By + C = 0, (1) parallel to the x axis, A = 0 B ≠ 0 C ≠ 0 y =- C / B ⑵ parallel to the y-axis, A ≠ 0 B = 0 C ≠ 0 x =- c / A ⑶ x axle with timely, A = 0 B ≠ 0 C = 0 y = 0 ⑷ and the y axle timely, A ≠ 0 B = 0 C = 0 x = 0 When ⑸ through the origin, C = A ^ 2 + B ^ 2 = 0
