Identify if the vectors (1, 2) and (3, 6) are independent or dependent.
Look for scalar multiples.
Are the vectors (2,1) and (1,-2) independent?
Check if you can express one in terms of the other.
What characterizes a set of linearly independent vectors?
Think about what it means for vectors to combine to zero.
True or False: The vectors (1, 2) and (2, 4) are linearly independent.
Check if one vector is a multiplier of the other.
Prove that the vectors (2, 3) and (2, 6) are dependent by showing a scalar relationship.
Form a linear combination to see if you can make zero.
Given vectors (3, 1) and (1, 3), find a linear combination that shows they are independent or dependent.
Try setting up the equation with scalars to see if it leads to a solution.
