I know that a vector is an arrow/ray kinda thing that you make using a triangle and I got this question that asks me to put two on the same grid: (4, -1) and 3(4, -1) Can you also teach me the basics of vectors? I'm new to this and it makes my brain hurt. Please gibe da help.

Generic.....here are some good videos to get you started : http://rootmath.org/linear-algebra/vector-basics

 

Here is the visual representation of your vectors:

 

 

Basically, vector v  is three times the length of vector u.....

 

Thus..... u = < 4, -1 >   and v = < 12, -3 >

 

cool cool cool
