Karnataka State Syllabus Class 9 Maths Chapter 10 Linear Equations in Two Variables Ex 10.4
Question 1.
Give the geometric representations of y = 3 as an equation.
(i) in one variable
(ii) in two variables.
Solution:
x + 3 = 0
i) In one variable, y = 3.
ii) In two variables, y = 3 straight line passes through (0, 3) parallel to x-axis. For any value of x, the value of y is 3.
Question 2.
Give the geometric representations of 2x + 9 = 0 as an equation.
(i) in one variable
(ii) in two variables.
Solution:
2x + 9 = 0, this equation in
i) One variable 2x + 9 =0
2x = -9
x = \(-\frac{9}{2}\) = -4.5
ii) 2x + 9 = 0 in two variables, 2x + 9 = 0. This equation passes through (-4.5, 0) and this is parallel ot y-axis. Coordinate of x = – 4.5
