Question

Find the equation of the line if the x-intercept and y-intercept are -2 and 4 respectively

• A. y - 2x - 4 = 0
• B. y + 2x - 4 = 0
• C. y - 2x + 4 = 0
• D. y + 2x + 4 = 0
• E. none of these

Answer 1

The correct option is A y - 2x - 4 = 0

The equation of line when x intercept and y intercept are a and b respectively is
$\frac{x}{a}+\frac{y}{b}=1$
Therefore, the required equation of line is
$\frac{x}{-2}+\frac{y}{4}=1$
$\Rightarrow -2x+y=4$
$\Rightarrow y-2x-4=0$
Option A is correct.
