Answer:


i = (4,0) , f= (-1,7)


v = <f_x -i_x , f_y -i_y>

Where:


i_x = 4, i_y = 0 , f_x = -1, f_y = 7

And replacing we got:


v =<-1-4, 7-0> =<-5, 7>

And then the olution for this case would be:

e. <-5, 7>

Explanation:

For this problem we know that we have a vector with the following initial and final points:


i = (4,0) , f= (-1,7)

Let v the vector if interest. And we want to find the component form from this info, so we can use the following formula:


v = <f_x -i_x , f_y -i_y>

Where:


i_x = 4, i_y = 0 , f_x = -1, f_y = 7

And replacing we got:


v =<-1-4, 7-0> =<-5, 7>

And then the olution for this case would be:

e. <-5, 7>
