Question

Which of the following points does not lie on the line 2x + 4y = 8?

• A. (0,2)
• B. (4,0)
• C. (2,1)
• D. (3,4)

Answer 1

The correct option is D

(3,4)

Substituting the points,

(a) (0,2)

2(0) + 4(2) = 8 which is equal to R.H.S

Hence the point (0,2) lies on the given line.

(b) (4,0)

2(4) + 4(0) = 8 which is equal to R.H.S

Hence the point (4,0) lies on the given line.

(c) (2,1)

2(2) + 4(1) = 8 which is equal to R.H.S

Hence the point (2,1) lies on the given line.

(d) (3,4)

2(3) + 4(4) = 8 which is not equal to R.H.S

Hence the point (3,4) does not lie on the given line.
