The video tutorial explains how to express vectors C and D as linear combinations of unit vectors I and J, and how to find their sum. It demonstrates expressing vectors in component form and calculating their sum by adding corresponding components. The tutorial also shows two methods to visualize the resultant vector on a coordinate plane: placing vector D at the terminal point of vector C and forming a parallelogram. The video aims to help viewers understand vector addition and visualization techniques.

What are vectors C and D expressed as in terms of unit vectors?

• C = -6I + 7J, D = 2I - 5J

• C = 6I - 7J, D = -2I + 5J

• C = -6I - 7J, D = 2I + 5J

• C = 6I + 7J, D = -2I - 5J
