Question 1
1 / -0

Which of the following points does not lie on the graph of the linear equation x – 4y = 0?

A
(1, 1)

B
(4, 1)

C
(8, 2)

D
(12, 3)

Solution

The given equation is x – 4y = 0, and the point (1, 1) doesn't lie on it because
1 – 4 × 1 = 0
– 3 ≠ 0
Question 2
1 / -0

Which of the following points lies on the graph of the linear equation 14x – 28 = 0?

A
(2, 0)

B
(0, 2)

C
(– 2, 0)

D
(0, – 2)

Solution

The given equation is 14x – 28 = 0 and one of its solutions is (2, 0).
14 × 2 – 28 = 0
0 = 0
Question 3
1 / -0

Which of the following points lies on the graph of the linear equation x = 3?

A
(2, 0)

B
(3, 0)

C
(4, 0)

D
(5, 0)

Solution

The graph of the equation x = 3 is a line parallel to y-axis.
Therefore, point (3, 0) lies on it.
Question 4
1 / -0

Which of the following ordered pairs represents a solution for the linear equation 3x + 4y = – 6?

A
(3, 3)

B
(– 2, 4)

C
(4, – 6)

D
(2, – 3)

Solution

The given equation is 3x + 4y = – 6 and the solution is (2, – 3).
3 × 2 + 4 x (– 3) = – 6
6 – 12 = – 6
– 6 = – 6
Question 5
1 / -0

Which of the following pairs of points lies on the graph of the linear equation x – 2y = 4?

A
(2, – 2)

B
(0, – 2)

C
(3, 2)

D
(4, 2)

Solution

x – 2y = 4 x = 0 and y = – 2 0 + 4 = 4
Question 6
1 / -0

Which of the following points does not lie on the graph of the linear equation 5x = 10?

A
(2, 0)

B
(2, 1)

C
(1, 2)

D
(2, 3)

Solution

The given linear equation is 5x = 10, and the point is (1, 2).
The graph of 5x = 10 or x = 2 is a line parallel to y-axis.
In the point (1, 2), x = 1 and y = 2.
Hence, this point does not lie on the graph of linear equation 5x = 10.
Question 7
1 / -0

Which of the following equations has its solution as (3, -4)?

A
11x + 15y = -27

B
18x – 4y = -35

C
-14x + 13y = -33

D
6x + 12y = 46

Solution

The solution (3, -4) can satisfy the equation 11x + 15y = -27.
As 11 × 3 + 15 × -4 = -27,
33 – 60 = -27
-27 = -27
So, the equation 11x + 15y = -27 has its solution as (3, -4).
Question 8
1 / -0

Which of the following points does not lie on the graph of the linear equation 2x = 4?

A
(2, – 1)

B
(2, 1)

C
(2, 7)

D
(– 1, 2)

Solution

The graph of the linear equation 2x = 4 is a line parallel to y-axis at x = 2.
In the solution (– 1, 2), the value of x = – 1.
Hence, (– 1, 2) does not lie on the graph of equation 2x = 4.
