find the slope of a line parallel to the line whose equation is $x + y = -4$. fully simplify your answer.
Answer
Explanation:
Step1: Convert the equation to slope - intercept form ($y = mx + b$)
Given $x + y=-4$, subtract $x$ from both sides: $$y=-x - 4$$ Here, the slope $m$ of the line $x + y=-4$ is $-1$.
Step2: Use the property of parallel lines
Parallel lines have the same slope.
Answer:
$-1$
