The equation is already in standard form. If you want to convert to slope-intercept form, then...



2x-y=-1 Start with the given equation.


-y=-1-2x Subtract 2x from both sides.


-y=-2x-1 Rearrange the terms.


y=%28-2x-1%29%2F%28-1%29 Divide both sides by -1 to isolate y.


y=%28%28-2%29%2F%28-1%29%29x%2B%28-1%29%2F%28-1%29 Break up the fraction.


y=2x%2B1 Reduce.


So the equation y=2x%2B1 is now in slope intercept form y=mx%2Bb where the slope is m=2 and the y-intercept is b=1 note: the y-intercept is the point
