+709 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.

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 >
