Answer

$y=-x+\dfrac{5}{2}$

Work Step by Step

Using $y=mx+b$, where $m$ is the slope and $b$ is the $y-$intercept, the equation of the line with the given slope $m= -1 $ and the given $y-$intercept $b= \dfrac{5}{2} $ is \begin{array}{l}\require{cancel} y=-1x+\dfrac{5}{2} \\\\ y=-x+\dfrac{5}{2} .\end{array}
