Answer:
The sum of vectors is <3,6>.
Step-by-step explanation:
The given vectors are <-2,-1> and <5,7>.
We need to find the sum of the given vectors and illustrate geometrically.
Plot the point (-2,-1) on a coordinate plane and draw a vector <a> from (0,0) to (-2,-1).
Plot the point (5,7) on a coordinate plane and draw a vector <b> from (0,0) to (5,7).
Now complete the parallelogram and the diagonal represents the sum of both vectors.
The end point of the diagonal is (3,6). It means sum of vectors is <3,6>.
Check the sum of vectors:
Therefore, the sum of vectors is <3,6>.
