Given three points, there is one line that can be drawn through them if the points are colinear. If the three points are noncolinear,there are three lines that can be drawn through pairs of points. For three points, three is the greatest number of lines that can be drawn through pairs of points. Determine the greatest number of lines that can be drawn for four points, five points, and six points in a plane. Gerneralize for n points.

Solution. The greatest number of lines that can be drawn for four points, ...
Solution Summary
The relationship between non-colinear points and lines drawn through them is investigated and generalized. The explanation is concise.

Find the possible failures in the column picture and the row picture, and match them up. Success would be 3 columns whose combinations give every vector b, which matches with 3 planes in the row picture that intersect at one point (the unique solution x). Give numerical examples of these two types of failure:
a. 3 columns lie
For the first 5 questions, consider the set of intersection points of two equations, and let a1 be the number of distinct affine real intersections with multiplicity one, let a2 be the number of distinct affine real intersections with multiplicity two, let b be the numberof distint complex non-real affine intersections and let
Look at the attached Gradebook report for a student (from a colleague). Do you, as a teacher think this is a valid tool to assess the student overall? What do you like about it? Dislike? What grade would you assign the student based on this? As a STUDENT, would you feel confident with validity and reliability of this grade r
Explore the following function. You are to decide which of threee lines given are tangent to the graph of f(x) at given points.
The function to define is
F(x)=2x^3-4x^2+3x-5
The possible tangent lines are:
y= x-5
y= 2x-5
y= 3x-5
a) what is/are the zero(es) for this function? In other words, what is the solu
