Question 2 Give the geometric representations of 2x + 9 = 0 as an equation (i) in one variable In one variable, there is only x axis.(No y-axis) Solving 2x + 9 = 0 2x = 9 x = 9/2 x = 4.5 Here, 2x + 9 = 0 is a point Hence, we can say that in one variable 2x + 9 = 0 is a point Question 2 Give the geometric representations of 2x + 9 = 0 as an equation (ii) in two variables In two variables, we have x and y axis Hence, writing equation 2x + 9 = 0 in terms of x & y 2x + 9 = 0 0 + 2x + 9 = 0 0y + 2x + 9 = 0 Plotting points on graph Comparison
