how do you turn 2y=x-1 into slope intercept form?

Uggh... we learned this last year. I think I remember. I'm pretty sure that it means that -1 is the place where the line starts, and then you would use 1 to make the line.

Since the number 1 is really the fraction 1/1 or 1 over 1, then to make the line on a chart you would go up 1, over 1, then put the dot, up 1 over 1, then put the dot, ex.

Hopefully I helped!
