Find an equation in slope-intercept form (where possible) for the line.
-$ y $-intercept $ -1, x $-intercept 2
A) $ y=-2 x+2 $
B) $ y=2 x+2 $
C) $ y=\frac{1}{2} x-1 $
D) $ y=-\frac{1}{2} x-1 $

The slope-intercept form is $y = mx + b$, where $m$ is the slope and $b$ is the y-intercept. The slope $m$ can be found using the points (2,0) and (0,-1), giving $m = \frac{-1-0}{0-2} = \frac{1}{2}$. Thus, with $b = -1$, the equation is $y = \frac{1}{2}x - 1$.
