(-2,2)(2,-8)
slope = (-8 - 2) / (2 - (-2) = -10/4 = -5/2

y = mx + b
slope(m) = -5/2
(-2,2)...x = - 2 and y = 2
now we sub and find b, the y int
2 = -5/2(-2) + b
2 = 5 + b
2 - 5 = b
-3 = b

so ur equation is : y = -5/2x - 3

1)The defining characteristic that separates invertebrates from other organisms is the absence of the spinal column and backbone.

A notochord, a dorsal hollow nerve cord, pharyngeal slits, post-ana.l tail.

2) Carbon dioxide is a waste product produced by the animal's cells during cellular respiration, as well as ammonia because it could be very toxic and is also a common by-product of animal waste due to the often inefficient conversion of feed nitrogen into animal product.

Answer from: bionicboy03120440

Check the picture below.

$\bf \textit{ellipse, horizontal major axis} \\\\ \cfrac{(x- h)^2}{ a^2}+\cfrac{(y- k)^2}{ b^2}=1 \qquad \begin{cases} center\ ( h, k)\\ vertices\ ( h\pm a, k)\\ c=\textit{distance from}\\ \qquad \textit{center to foci}\\ \qquad \sqrt{ a ^2- b ^2} \end{cases} \\\\[-0.35em] ~\dotfill\\\\ \begin{cases} h=0\\ k=0\\ a=3\\ b=2 \end{cases}\implies \cfrac{(x- 0)^2}{ 3^2}+\cfrac{(y- 0)^2}{ 2^2}=1\implies \cfrac{x^2}{9}+\cfrac{y^2}{4}=1$

Write an equation of an ellipse in standard form with the center at the origin and with the given ch

Answer from: bezar77

Option A

The equation of ellipse in standard form is $\frac{x^{2}}{9}+\frac{y^{2}}{4}=1$

Solution:

Given, We have to write an equation of an ellipse in standard form with the center at the origin

Given that vertex at (-3,0) and co-vertex (0,2)

The standard form of an ellipse is $\frac{x^{2}}{a^{2}}+\frac{y^{2}}{b^{2}}=1$

where a is x- intercept and b is y – intercept.

We have vertex (-3, 0) and (0, 2) from these we can say that, x – intercept is – 3 and y – intercept is 2 . As we know that intercepts are the respective values when other variables becomes 0.

Now, let us find our ellipse equation:

$\begin{array}{l}{\rightarrow \frac{x^{2}}{(-3)^{2}}+\frac{y^{2}}{2^{2}}=1} \\\\ {\rightarrow \frac{x^{2}}{9}+\frac{y^{2}}{4}=1}\end{array}$

Hence, the standard form equation is $\frac{x^{2}}{9}+\frac{y^{2}}{4}=1$

Thus option A is correct

Answer from: wendyyy7774

The correct answers are:

B-Loyalty and obedience were valued traits.

C-Power belonged to the king and nobles.

F-Peasants paid taxes for protection from enemy nobles and knights.

Explanation:

In a feudal system it was very difficult for someone to move between social classes. Also, people did not typically resist the King as they were seen as the 'natural' leaders and in many cases, chosen by God.

Also, the Kings did not grant land based on education. Lands and vassals were made based on the of military power that could be sent to the King when in need.

Apart from that, for feudalism to work, Loyalty and Obedience were valued. The whole system was controlled by the powerful Kings and local noble families who held a lot of power. Peasants should pay taxes to the nobles and local knights for protection and to work on the land.
