Question

Which vectors represent the reflection of the vector <3, -7> across the x-axis? A. [3/7} B. [-3/7] C. <-3, 7> D. <3, 7> E. [7/-3] F. <7, -3>

Answer 1

D) < 3, 7)>

Explanation:

Explanation:-

Given that the vector < 3 , -7 >

Given the vector reflection across the x-axis

(x,y) → (x , -y)

The vector < 3,-7> →< 3, -(-7)>

< 3,-7> →< 3, 7)>
