Which of the point-slope equations below are correct for the line that passes through the points (6,6) and (3,1)?

1 answer:

4 0

(6,6)(3,1)
slope(m) = (1 - 6) / (3 - 6) = -5/-3 = 5/3

y - y1 = m(x - x1)...using (6,6)
y - 6 = 5/3(x - 6) <== here is one

y - y1 = m(x - x1)...using (3,1)
y - 1 = 5/3(x - 3) <== here is the other one

Find the vertex and length of the latus rectum for the parabola. y=1/6(x-8)^2+6

Ivan

Step-by-step explanation:

If the parabola has the form

$y = a(x - h)^2 + k$ (vertex form)

then its vertex is located at the point (h, k). Therefore, the vertex of the parabola

$y = \dfrac{1}{6}(x - 8)^2 + 6$

is located at the point (8, 6).

To find the length of the parabola's latus rectum, we need to find its focal length f. Luckily, since our equation is in vertex form, we can easily find from the focus (or focal point) coordinate, which is

$\text{focus} = (h, k +\frac{1}{4a})$

where $\frac{1}{4a}$ is called the focal length or distance of the focus from the vertex. So from our equation, we can see that the focal length f is

$f = \dfrac{1}{4(\frac{1}{6})} = \dfrac{3}{2}$

By definition, the length of the latus rectum is four times the focal length so therefore, its value is

$\text{latus rectum} = 4\left(\dfrac{3}{2}\right) = 6$
