The vertex is (-1, 2).
The equation of parabola:
where (h, k) is the vertex
We have h = -1 and k = 2.
Substitute:

Answer: y= -1/2x + 3.5
Step-by-step explanation:
y=mx+b
Y-3= -1/2(x-1)
y-3= -1/2x+1/2
+3 +3
y= -1/2x + 3.5
It’s B because 25x the x represents what 25 is multiplied by and b is the only one that makes since mark me brainliest please
