Question

1. find the slope of a line parallel to the line whose equation is ( x + y = 1 ). fully simplify your answer.

Explanation:

Step1: Rewrite in slope-intercept form

Rearrange $x + y = 1$ to $y = -x + 1$.

Step2: Identify the slope

For $y=mx+b$, slope $m=-1$.

Step3: Parallel lines have equal slopes

Parallel line slope = $-1$.

Answer:

$-1$
