**KSEEB Solutions for Class 9 Maths Chapter 10 Linear Equations in Two Variables Ex 10.4** are part of KSEEB Solutions for Class 9 Maths. Here we have given Karnataka Board Class 9 Maths Chapter 10 Linear Equations in Two Variables Exercise 10.4.

## Karnataka Board 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 straightline passes through (0, 3) parallel to x-axis. For any value of x, 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
