Selina Concise Mathematics Class 9 ICSE Solutions Graphical Solution (Solution of Simultaneous Linear Equations, Graphically) Selina ICSE Solutions for Class 9 Maths Chapter 27 Graphical Solution (Solution of Simultaneous Linear Equations, Graphically) Exercise 27(A) 1.Draw the graph for each equation, given below: (i) x = 5 (ii) x + 5 = 0 (iii) y = 7 (iv) y + 7 = 0 (v) 2x + 3y = 0 (vi) 3x + 2y = 6 (vii) x - 5y + 4 = 0 (viii) 5x + y + 5 = 0 Solution 1: (i) The graph x= 5 in the following figure is a straight line AB which is parallel to y axis at a distance of 5 units from it. (ii) x+5=0 x = -5 The graph x= -5 in the following figure is a straight line AB which is parallel to y axis at a distance of 5 units from it in the negative x direction. (iii) The graph y = 7 in the following figure is a straight line AB which is parallel to x axis at a distance of 7 units from it. (iv) y + 7 = 0 y = -7 The graph y = -7 in the following figure is a str...
