Question

Write the equation of the line $x+2y-4=0$ in slope intercept form and then find the slope and the $y$-intercept of the line.

Answer 1

$x+2y-4=0$

$\Rightarrow 2y=-x+4$

$\Rightarrow y=-\frac{1}{2}x+2$,divide both sides by $2$

Comparing with $y=mx+c$

Slope $m=-\frac{1}{2}$ and $y-$ intercept $=c=2$
