CBSE TEST PAPER-03 CLASS –IX Mathematics (Linear Equation in two Variables)
1.
x = −5 can be written in as equation in two variable
[1] (d) Both b and c
(a) 1. X + 1.Y = 5 2.
(b) 1.x + 0. y = −5
(c) 1.x + 0. y + 5 = 0
The reason that a degree one polynomial equation ax + by + c = 0 is called a linear [1] equation is that (a) It has infinitely many solution (b) The geometrical representation is a straight line (c) It has two variable (d) Both a and b
3.
Select the equation where graph is given below (a) y = 2 x (b) y = 2 x + 1 (c) y = 2 x − 4 (d) x − y = 0
