Answer:

True

Step-by-step explanation:

In an ellipse, the longer axis is called the major axis and the shorter axis called the minor axis . Vertices are the endpoints of major axis and co-vertices are the endpoints of minor axis.

The midpoint of major and minor axis is known as the centre of ellipse.

Foci are the the two points on the major axis of the ellipse such that sum of distance of the foci from the point on the ellipse is constant.

Foci basically lie on the major axis.

So, the given statement ''the focus of an ellipse lie on the major axis of the ellipse'' is true.

We have slope intercept form. Parallel means the same slope, and we get to choose the intercept to fit the new point (-6,0).

y = (1/3) x + b

0 = (1/3) (-6) + b

2 = b

Answer y = (1/3) x + 2 third choice

Given the line below.

geniusboy [140]

Answer:

The equation of the line in point slope form is equal to

$y+2=(x+2)$

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

(-2,-2) and (2,2)

substitute the values

$m=\frac{2+2}{2+2}=1$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=1\\(x1,y1)=(-2,-2)$

substitute the values in the formula

$y-(-2)=(1)(x-(-2))$

$y+2=(x+2)$

Write and equation in point-slope form for the line that passes through the points (-1,4) And is perpendicular to the line Y=-2x

miv72 [106K]

since it is perpendicular line you have to change thing signs of the equation.

x y

(-1,4)

replace the (-1) with x and (4) with y

y=1/2x+b

4=1/2(-1)+b

4=-1/2+b

4+1/2=b

9/2=b

therefore, the perpendicular line is y=1/2x+9/2
