how do you graph –x + 2y = -2 and find the x-intercept, the y-intercept, and slope i know you have to chang it in to y=mx+b but that is about it haha

$\displaystyle -x + 2y = -2$ $\displaystyle -x +x+ 2y = -2+x$ $\displaystyle 2y = -2+x$ $\displaystyle y = \frac{-2}{2}+\frac{x}{2}$ $\displaystyle y = \frac{x}{2}-1$ To find the x-intercepy make y =0 and to find the y-intercept make x=0.
[SIZE=3]ok so –x + 2y = -2get y=1/2x
