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.

Write an equation for the line parallel to the given line that contains C<br> C(2,6); y= -4x + 7

MrRa [10]

Answer:

$y=-4x+14$

Step-by-step explanation:

step 1

Find the slope of the given line

we have

$y=-4x+7$

This is the equation of the given line in slope intercept form

The slope is $m=-4$

step 2

Find the slope of the line parallel to the given line

we know that

If two lines are parallel, then their slopes are the same

therefore

The slope of the line parallel to to the given line is $m=-4$

step 3

Find the equation of the line in point slope form

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

we have

$m=-4$

$C\ (2,6)$

substitute

$y-6=-4(x-2)$

step 4

Convert to slope intercept form

$y-6=-4(x-2)$

isolate the variable y

$y-6=-4x+8$

$y=-4x+8+6$

$y=-4x+14$
