Which equation has a graph that is a parabola with a vertex at (-1, -1)?

y=-1 and x=-1

Step-by-step explanation:

10x/-10y=-1 y=-1 same with x=-1

here is a different equation

12x(-1)=(144/12y)=x and y

x=-y

y=-x

-y=-1y because if there is no variable it is 1 or -1 depending if its a - Symbol

same with -x=-1x
