Just like line segments or lines, you just need two points to name them. Line ---.-----.-----------------.--------------> A B C D Line= AB Line= BC Ray= CD

Two points determine a unique line. Therefore, there are infinitely many circles that can pass through two given points. This is because a circle can be defined by its center, which can lie anywhere along the perpendicular bisector of the line segment connecting the two points.
exactly one
The slope (m) = (delta y)/(delta x) m= (y2-y1)/(x2-x1) Given two points A(a,b) C(c,d) if A is the starting point (x1,y1) and C is the ending point (x2,y2) then m= (d-b)/(c-a) OR if C is the starting point then, m=(b-d)/(a-c) both will give you the same answer.

There are one or infinitely many points.
10 lines, but only if no three of them are collinear.
A line must be in 2-dimensional space to have a slope. In 2-d space, each point is identified by an ordered pair of coordinates. The points in the question are not and so it is not possible to answer the question.
Linear means line so collinear means on the same line. Non-collinear then means not on the same line. Hope that helped =D

The coordinate of what?
A tetrahedron is a 3-D object so the drawing will be a 2-D projection of a 3-D object. Mark four points so that no three of them are on the same straight line. Then join up each of the six pairs of points.
The slope of a line is determined using the coordinates of at least 2 points on the line. If you have 2 points (A, B) and (C, D), the slope of the line can be determined using the formula (B - D) / (A - C) or (D - B) / (C - A) which is essentially the difference of the y-coordinates divided by the difference of the x - coordinates. Alternately, you could think of it as "rise over run", the increase in height (change in y) between the two points over the horizontal distance traveled (change in x).
Given two points, P = (a, b) and Q = (c, d), the slope is (b - d)/(a - c) provided a is different from c. If a = c then the line is vertical and the slope is not defined.
