Question

Vector A is transformed to vector B. Identify the transformation.

Answer 1

Step 1:

The rule for a reflection over the x -axis is (x,y)→(x,−y) .

Step 2:

Write the coordinates of A

The coordinate of A = ( 3 , 1 )

Step 3:

If A is reflected over x-axis, it will form B with coordinates ( 3 , -1)

Final answer

$\begin{gathered} \text{Option C} \\ A\begin{bmatrix}{3} & {} \\ {1} & {}\end{bmatrix}\text{ is reflected over the x-axis to B }\begin{bmatrix}{3} & {} \\ {-1} & {}\end{bmatrix} \end{gathered}$
