Can somebody help me with this parabola?

Okey im working in a math assignment of parabolas, and I have two exercices left. One of them when I solve it, it does not give me a parabola but I cant find the error:

‘2= to the second power…ok

-x’2=-y+2x-6

Y=x’2+2x-6

Now I use the formula b over a by 2: x=-b/a(2)

X=-2/1(2)…x= -1

Y=-1’2+2(-1)-6

Y=1+-2-6

Y=-7 vertex = (-1,-7) Why intercept = (0, -6)

Now I choose any number to find the other ordered pair

Y= 2’2+2(2)-6

Y=4+4-6

Y=2 2nd ordered pair= (2,2)

But when I graph it it does not give me a parabola ):
