Question

Rewrite the equation of a straight line in a slope - intercept form x + 2y + 1 = 0

Answer 1

Answer:

y = -x/2 -1/2

Step-by-step explanation:

$x + 2y + 1 = 0$

Write in the y=mx+b form

$2y =-x-1+0\\2y =-x-1$

Divide both sides by 2

$\frac{2y}{2} =\frac{-1x}{2} -\frac{1}{2} \\\\y = -\frac{x}{2} -\frac{1}{2}$
