Answer 1

Vectors

Vectors can be represented in a rectangular grid. We only need the endpoint of the vector, then we join the origin (0, 0) with the terminal point and we draw the vector.

It's given the vectors:

a = < 2, -1 > b = < 1, 3 >

Now we represent both vectors in the rectangular grid as follows:

Now we add both vectors by using the parallelogram method which consists in forming a parallelogram by drawing a line parallel to a that passes through the terminal point of b and a parallel line to b that passes through the terminal point of a, as follows:

The sum of a + b is drawn in black and its coordinates are < 3, 2 >
