Answer 2

To find the vector result of a - 3b, we need to perform vector subtraction and scalar multiplication.

Given vectors: a = (1, 1) b = (0, 1)

To calculate a - 3b, we perform the following steps:

1. Perform scalar multiplication of vector b by the scalar -3: -3b = -3 * (0, 1) = (0, -3)

2. Perform vector subtraction of a and -3b: a - 3b = (1, 1) - (0, -3) = (1 - 0, 1 - (-3)) = (1, 4)

So, the result of the vector operation a - 3b is (1, 4).
