MCQ Questions for Class 9 Maths Chapter 4 Linear Equations in Two Variables with Answers

MCQs from Class 9 Maths Chapter 4 – Linear Equations in Two Variables are provided here to help students prepare for their upcoming Maths exam.

MCQs from CBSE Class 9 Maths Chapter 4: Linear Equations in Two Variables

1. The linear equation 3x-11y=10 has:
a) Unique solution
b) Two solutions
c) Infinitely many solutions
d) No solutions

Answer/Explanation

Answer: (c)
Explanation: 3x-11y=10

y=(10-3x)/11

Now for infinite values of x, y will also have the infinite solutions.


2. 3x+10 = 0 will has:
a) Unique solution
b) Two solutions
c) Infinitely many solutions
d) No solutions

Answer/Explanation

Answer:(a)
Explanation: 3x+10 = 0

x = -10/3.

Hence, only one solution is possible.


3. The solution of equation x-2y = 4 is:
a) (0,2)
b) (2,0)
c) (4,0)
d) (1,1)

Answer/Explanation

Answer: (c)
Explanation: Putting x=4 and y = 0, on the L.H.S. of the given equation, we get;

4-2(0) = 4 – 0 = 4

Which is equal to R.H.S.


4. The value of k, if x = 1, y = 2 is a solution of the equation 2x + 3y = k.
a) 5
b) 6
c) 7
d) 8

Answer/Explanation

Answer: (d)
Explanation: 2x + 3y = k

k=2(1)+3(2) = 2+6 = 8


5. Point (3, 4) lies on the graph of the equation 3y = kx + 7. The value of k is:
a) 4/3
b) 5/3
c) 3
d) 7/3

Answer/Explanation

Answer:(b)
Explanation: 3y = kx + 7

Here, x = 3 and y = 4

Hence,

(3×4) = (kx3) + 7

12 = 3k+7

3k = 12–7

3k = 5

k = 5/3


6. The graph of linear equation x+2y = 2, cuts the y-axis at:
a) (2,0)
b) (0,2)
c) (0,1)
d) (1,1)

Answer/Explanation

Answer: (c)
Explanation: x+2y = 2

y = (2-x)/2

If x=0, then;

y=(2-0)/2 = 2/2 = 1

Hence, x+3y=2 cuts y-axis at (0,1).

1. Can we write 0 in the form of p/q?
a. Yes
b. No
c. Cannot be explained
d. None of the above

Answer/Explanation

Answer: (a)
Explanation: 0 is a rational number and hence it can be written in the form of p/q.

Example: 0/4 = 0


2.) The three rational numbers between 3 and 4 are:
a. 5/2,6/2,7/2
b. 13/4,14/4,15/4
c. 12/7,13/7,14/7
d.11/4,12/4,13/4

Answer/Explanation

Answer: (b)
Explanation: There are many rational numbers in between 3 and 4

To find 3 rational numbers, we need to multiply and divide both the numbers by 3+1 = 4

Hence, 3 x (4/4) = 12/4 and 4 x (4/4) = 16/4

Thus, three rational numbers between 12/4 and 16/4 are 13/4, 14/4 and 15/4.


3.) In between any two numbers there are:
a. Only one rational number
b. Many rational numbers
