How to solve
Scalar multiplication stretches each component; vector addition adds matching components.
Steps
- Multiply each vector by its scalar componentwise.
- Add the x-components together and the y-components together.
- Write the result as a vector.
Example
2(3, −1) + 3(1, 2)
- 2(3, −1) = (6, −2).
- 3(1, 2) = (3, 6).
- (6+3, −2+6) = (9, 4).
Answer: (9, 4)
How to type answers
- Write vectors like (9, 4)
