Given:

The pair of end points: (3,-8) and (3,-1).

To find:

Whether the given pair of endpoints lies on the same horizontal or vertical line.

Solution:

If the x-coordinates of pair of endpoints are same, then the pair of endpoints lies on the same vertical.

If the y-coordinates of pair of endpoints are same, then the pair of endpoints lies on the same horizontal.

The given endpoints are (3,-8) and (3,-1).

From the given endpoints, it is clear that the x-coordinates of the endpoints are same. So, the given endpoints lies on the same vertical line.

The length of the line segment that joins the pair of points is

$D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$D=\sqrt{(3-3)^2+(-1-(-8))^2}$

$D=\sqrt{(0)^2+(-1+8)^2}$

$D=\sqrt{(7)^2}$

D=7

Therefore, the given endpoints lies on the same vertical line and the length of the line segment is 7 units.

step-by-step explanation:

line segment bisector. definition: a line, ray or segment which cuts another line segment into two equal parts. try this drag one of the orange dots at a or b and note the the line ab always divides the line pq into two equal parts.

la parábola es el lugar

geométrico en el cual los puntos tienen una distancia idéntica, equidistantes,

de un punto denominado foco, f, y una recta denominada directriz

el radio vector de una

parábola es el segmento que existe entre un punto cualquiera y el foco.

por la ecuación se observa

que la parábola abre hacia la derecha, por lo cual podemos usar las siguientes fórmulas

la ecuación ordinaria de la

parábola es y^2 = 4px, donde p es la longitud desde el vértice de la parábola al

foco.

la fórmula de la directriz

es x + p = 0

resolviendo:

y^2-9x = 0

y^2 = 9x

4p = 9, entonces p = 9/4

entonces el foco tendrá la

coordenada f(9/4,0)

la directriz vendrá

expresada por

x + p = 0

x = -p

x = -9/4

el problema indica que la

ordenada es igual a 6, entonces

(6)^2=9x

x = 36/9

x = 4

entonces el punto al cual

hay que obtener la distancia será p(4,6)

calculando se tendrá: pf =

pf = 6,25 u
