Question

Which of the following represents the translation of M (8,-2) along vector<-5, 1 > and its reflection

Answer 1

Step-by-step explanation:

M(8.-2), M'(x,y) , $\overrightarrow{v}$ =(-5,1)

$\overrightarrow{MM'} = \overrightarrow{v}$

--> x - 8 = -5 --> x= 3

---> y+2 = 1 --> y =-1

so M'(3,-1) and its reflection y-axis is (-3,-1)
