You do this by converting to vertex form a(x - b)^2 + c where the axis of symmetry is x = b
the correct function to have a symmetry x = 3 will be the one which includes -6x
which is the last one
x^2 - 6x - 1 = (x - 3)^2 -9-1
the last option is the correct one
Answer:
The slope is 1/2
Step-by-step explanation:
I did rise over run
Slope intercept form is

where

is the slope
and

is the y-intercept
they give us that the slope is 2
so our

then to find

, we temporarily plug in the point they gave us for x and y
so

and solve for

3 = 2 + b
1 = b
so our

put this together and we get

as our answer
