The solution of a linear equation in two variables is a pair of numbers, one for x and one for y which satisfies the equation There are infinitely many solutions for a linear equation in two variables For example, x2y = 6 is a linear equation and some of its solution are (0,3),(6,0),(2,2) because, they satisfy x2y = 6 Graphing of Linear Equation in Two Variables NCERT Exemplar Class 9 Maths Chapter 4 Exercise 44 Question 1 Show that the points A (1, 2), B (1, 16) and C (0, – 7) lie on the graph of the linear equation y = 9x – 7 Solution Firstly, to draw the graph of equation y = 9x – 7, we need atleast two solutions When x = 2, then y = 9 (2) – 7 = 18 – 7 = 11 Ex 43, 1 Draw the graph of each of the following linear equations in two variables x y = 4 x y = 4 To draw the graph, we need at least

Method 1 using two points to graph a linear equation The graph of any linear equation like y = 3 x 2 or y = − x 9 is a line, and only two points are needed to define a line The idea with this method is to find two points on the line by picking values of x Since there are infinite lines passing through the point (2, 3) Let, first equation is x y = 5 and second equation is 2x 3y = 13 Clearly, the lines represented by both equations intersect at the point (2, 3) 24 Let y varies directly as x Ify = 12 when x = 4, then write a linear equation What is the value of y,when x = 5 ?The graph of the linear equation 3x 4y = 12 cuts the yaxis at the point where x = 0 On putting x = 0 in the given equation, we have 4 y = 12, which gives y = 3 Thus, the

 Step 1 Rearrange the equation into standard form Add y to both sides x − yy = 2y ⇒ x 0 = 2 y Subtract 2 from both sides ⇒ x−2 = 2−2 y ⇒ x − 2 = 0 y y = x −2 '~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~For x = 4, y = 4, therefore (4, 4) satisfies the linear equation y = x By plotting the points (1,1) and (4, 4) on the graph paper and joining them by a line, we obtain the graph of y = x The given equation is y = – xWhen x = 4, we have y = 4 2 = 2
