Question

The slope intercept form of the line $\frac{x}{2}+\frac{y}{4}=1$ is

• A. $y=-2x+4$
• B. $y=2x+4$
• C. $y=4x+2$
• D. $y=-4x+2$

Answer 1

The correct option is A $y=-2x+4$

$\frac{x}{2}+\frac{y}{4}=1$
$\Rightarrow 4x+2y=8\Rightarrow 2x+y=4$
$\Rightarrow y=-2x+4$
Here slope is $-2$, and intercept is $4$
