Which of the following pairs of points can be used to draw the line represented by the equation \(2x+y=4\)?

Answer and explanation

Correct answer: (0,4) और (2,0)

Putting \(x=0\) in \(2x+y=4\) gives \(y=4\), so \((0,4)\) lies on the line. Putting \(y=0\) gives \(2x=4\), hence \(x=2\), so \((2,0)\) is the second point. The points in option B do not satisfy the equation; for example, substituting \((4,0)\) gives a left side of 8. Exam tip: To obtain two convenient points, set \(x=0\) and \(y=0\) successively.
