Answer:
y = 2x
Step-by-step explanation:
We can find the slope
m = (y2-y1)/ (x2-x1)
= (4--4)/(2--2)
= (4+4)/(2+2)
= (8/4)
= 2
We can use the point slope form of the equation
y-y1 = m(x-x1)
y--4 = 2(x--2)
y+4 = 2(x+2)
Distribute the 2
y+4 = 2x+4
Subtract 4 from each side
y+4-4 = 2x+4-4
y = 2x
y+2 = 2x+4
Answer:
(a) (x -3)^2 = -6(y +5.5)
Step-by-step explanation:
The equation of a parabola can be written as ...
(x -h)^2 = 4p(y -k)
where (h, k) is the vertex, and p is the distance from the focus to the vertex.
The vertex is half-way between the focus and directrix, so is ...
(h, k) = (1/2)((3, -7) +(3, -4)) = (3, -5.5)
The focus is at y=-7, and the vertex is at y=-5.5, so the distance between them is ...
-7 -(-5.5) = -1.5
Then the equation for the parabola is ...
(x -3)^2 = 4(-1.5)(y -(-5.5))
(x -3)^2 = -6(y +5.5) . . . . matches the first choice
