Answer
$I$
Work Step by Step
In order to determine the $y$-intercept and slope more easily, we want to rewrite each equation in the slope-intercept form, which is given by:
$$y = mx + b$$ where $m$ is the slope of the line and $b$ is the $y$-intercept.
Substitute the values of the slope and $y$-intercept into the equation above to obtain $y=-2x+3$
Thus, the answer is option $I$.
