Question

The intercept cut off from y-axis is twice that from x-axis by the line and line is passes through (1, 2) then its equation is-

• A. 2x + y = 4
• B. 2x + y + 4 = 0
• C. 2x –y = 4
• D. 2x – y + 4 = 0

Answer 1

Answer: (A)

2x + y = 4

Answer 2

Let the equation

given b = 2a

\ … (1)

it passes through (1, 2)

\ + = 1

a = 2

$\frac { x } { 2 } + \frac { y } { 4 }$ = 1 Ž 2x + y = 4
