Answer:
the vertex of the parabola is:(-2,0)
the focus of the parabola is:(-2,
)
the directrix of the parabola is:y=
Step-by-step explanation:
we know that for any general equation of the parabola of the type 
the vertex of the parabola is given by (h,k)
where 
and 
therefore by the given data we have h=-2 and k=0
hence vertex=(-2,0)
the general equation of the parabola of the type 
; the parabola symmetric around the y-axis has the focus from the centre i.e. the vertex (h,k) at a distance a as (h,k+a) and the directrix is given by y=k-a
so focus is 
now the directrix of the parabola is 
.
Answer:72
Step-by-step explanation:because idk
Answer:
y=-5.5x+-5
Step-by-step explanation:
<em>the slope is -5.5</em>
<em>the y-intercept is what the y-axis is when the x-axis is zero</em>
<em>therefore the y-intercept is -5</em>
hope this helps
have a nice day!!
