Answer:
Explanation:
To find the difference between vectors a and b, we subtract the corresponding components of the vectors.
Given that a = ⟨ -7, 2 ⟩ and b = ⟨ 7, 2 ⟩, we can calculate the difference a - b as follows:
a - b = ⟨ -7, 2 ⟩ - ⟨ 7, 2 ⟩
Subtracting the corresponding components:
a - b = ⟨ -7 - 7, 2 - 2 ⟩
Simplifying:
a - b = ⟨ -14, 0 ⟩
Therefore, the difference a - b is ⟨ -14, 0 ⟩.
