If I told you, would it really be your own words?

A vector indicates both a magnitude and a direction. What can you represent with a scalar?

Again, a vector gives a magnitude and a direction. For a, our magnitude is 8, and our direction is west of south. For b, the direction of the force should be opposite that of gravity.

Two vectors are equal if they have the same magnitude and the same direction. So, your goal for the first part is to find a vector with

the same magnitude and direction as . Now, what section of the line is three times the length of ? From to is , from to is , and from to is , correct? And any vector drawn between two points on that line should run parallel to , so you should have equal magnitude and equal direction. Do you see?

Solve part b the same way.
