Answer:
Correct, as 4 is the only number repeating twice
Answer:
1st
Vertex
we have
f(x)=x²-18x+88
let
y=x²-18x+88
comparing above equation with ax²+bx+c
we get
a=1
b=-18
c=88
now
vertex(x,y)=(-b/2a,f(-b/2a))
x=(18/2×1)=9
y=f(9)=9²-18×9+88=7
SO
VERTEX(X,Y)=(9,7)

I can’t really see the picture . I need a better one
M = slope
Lets put this in point slope form, and slope intercept form.
y - 6 = -1/2(x - 6)
y - 6 = -1/2x + 3
+ 6 + 6
y = -1/2x + 9
Answer: y = -1/2x + 9
