A line is an undefined term because it

It is undefined because it is one of the building blocks of geometry.
In order to define a term, we must have a definition of all of the words used to describe it. As this progresses, we would have a never-ending list of words to define; at some point, we must accept a few basic building blocks as being undefined.

Answer:

Step-by-step explanation:

A line is open from both sides from left hand side and right hand side.

It can be extended from both the sides which will lead it toward either $-\infty\text{or}\infty$ which is why it is said to be undefined.

If we take general equation of a line

y=m x+c

Its domain is all real numbers and its range is also all real numbers.

Real numbers can also be represented as $(-\infty,\infty)$ .This is another way of writing the entire real number line.

So here, ABCD is being inscribed in a circle, so ABCD is a cyclic quadrilateral (as inscribed in a circle) also, there exists a property of cyclic quadrilateral, i.e, the sum of opposite angles of a cyclic quadrilateral is 180°, so we can just write the following equation using this :

${:\implies \quad \sf y^{\circ}+83^{\circ}=180^{\circ}}$

${:\implies \quad \sf y^{\circ}=180^{\circ}-83^{\circ}}$

${:\implies \quad \sf y^{\circ}=97^{\circ}}$

${:\implies \quad \boxed{\bf{y=97}}}$

Directed line segment DE has endpoints D(-4,-2) and E(1,8). Point F divides DE such that DF:FE is 3:2What are the coordinates of

VMariaS [17]

The Solution.

The given points are

$D(-4,-2)\text{ and E(1,8)}$

The formula is

$\frac{mx_2+nx_1}{m+n}_{},\frac{my_2+ny_1}{m+n}$

In this case,

$m=3,n=2$

Therefore,

$\begin{gathered} (\frac{mx_2+nx_1}{m+n}_{},\frac{my_2+ny_1}{m+n}) \\ =(\frac{3(1)+_{}2(-4)_{}}{3+2}_{},\frac{3(8)_{}+2(-2)_{}}{3+2}) \\ \end{gathered}$ $=(\frac{3-8}{5},\frac{24-4}{5})=(-\frac{5}{5},\frac{20}{5})$ $=(-1,4)$

Hence, the correct answer is (-1, 4) (option 3)
