Although you didn't provide a list of options to choose from, I hope my explanation will help you work this out with ease. :)
This equation is in a form known as "standard form." ax+by=c Standard form is commonly used, however for comparing slopes, there is a more efficient equation to use.
Point-slope form (y=mx+b) allows lines' slopes (y) and y-intercepts (b) to be quickly compared and contrasted. Let's put the equation into this form.
2x-y=-1
-2x -2x
-y = -1 - 2x
*-1 *-1
y= 1 + 2x
Switch pieces around
y= 2x + 1
The slope is 2, the y intercept is 1.
