Work Step by Step

Using $y=mx+b$, the given equation, $ y=-x+1 ,$ has the following characteristics: \begin{array}{l}\require{cancel} \text{Slope: } m=-1 \\\text{$y$-intercept: } b=1 .\end{array} To graph this line, start with the $y-$intercept of $( 0,1 )$. From the $y-$intercept, the slope, $m= -1=\dfrac{-1}{1} $ can be interpreted as moving $1$ unit down and $1$ unit to the right. Hence, the second point for graphing is the point $( 1,0 )$.
