Default algebra two graphing

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

-x + 2y = -2

-x +x+ 2y = -2+x

2y = -2+x

y = \frac{-2}{2}+\frac{x}{2}

y = \frac{x}{2}-1

To find the x-intercepy make y =0 and to find the y-intercept make x=0.
