Question

Reflect the vector (-3,5) acrossthe x-axis.([?],[])

Answer 1

1) When we reflex across the x-axis we must follow this rule:

Pre-image Image

(x, y) ----------------> (x,-y)

2) Since we have a vector <-3,5> then reflecting it across the x-axis we'll have

Pre-image Image

<-3,5>---------> <-3, -5>

3) So the vector after the reflection is < -3,-5>
