Did you read my tips on how to study and learn Math 1300?  If not, here is a link to those important suggestions:

Here is a link to the actual assignment, in case you don't have it handy:

Note that you need to study Lesson 1 (Systems of Linear Equations) and Lesson 9 (Vectors) from my Linear Algebra & Vector Geometry book to prepare for this assignment.  I think you should find this assignment fairly straightforward if you do thoroughly study and do all the Practise Problems I give you in Lesson 9.  However, make sure that you study Lesson 1 of my book first.  It is an important review of key skills you will need throughout the course and assignments.

Besides thoroughly studying Lesson 9 in my book, you may find questions 29, 30 and 31 in my Practise Problems for that lesson helpful in understanding the kind of things to do for this question.

Standard stuff.

Think about the arrows you can draw and how you know if vectors are collinear or not.

Anytime angles are involved, consider the formulas for cosine or sine of an angle between two vectors.  You may also find question 1 in my Practise Problems of some help with how to solve this problem.

More of the same.

A challenging question, but you may find question 7 in my Lecture Problems (at the front of Lesson 9 and discussed in my lecture notes, not the Practise Problems) of some help.

Understand that the picture they have drawn is in three dimensions.  Visualize the x-axis running west-east on your page, the y-axis running north-south, and the z-axis rising up like a pole from your table top.  Note that A, B and C are the x-, y- and z-intercepts, respectively.  To find an intercept, you merely sub 0 in place of the other variables.  For example, the x-intercept is when y and z are both 0.
