Question

Which of the following points does not lie on the graph of the equation 3x – 2y + 4 = 0 ?

(A) (2, 5)

(B) (1, 2)

(C) 4, 8)

(D) (–2, – 1)

Answer 1

The correct option is: (B)**(1, 2)**

Explanation.

Given equation is 3x – 2y + 4 = 0

For point (2 , 5)

3 (2) – 2(5) + 4

6 – 10 + 4

= 0 (lie on the equation)

For point (1 , 2)

3(1) – 2(2) + 4

3 – 4 + 4 = 3 (does not lie)

For point (4 , 8)

3(4) – 2(8) + 4 = 0 (lie)

For point (– 2 , – 1)

3 (– 2) – 2 (– 1) + 4 = 0 (lie)

Answer is (1 , 2)
