If you are going from (5,0) to (15,0)

then you solve 5k = 15 for k to get your answer

So then it would be 3?

jim_thompson5910 · Answer

that's if you start with (5,0) and end up with (15,0), yes

jim_thompson5910 · Answer

notice how (15,0) is 3 times further away from O(0,0) as compared to (5,0)

anonymous · Answer

so then it would be -3 right?

jim_thompson5910 · Answer

how are you getting -3?

anonymous · Answer

its going from 5,0 to 15,0 so it would just be 3?

jim_thompson5910 · Answer

yep
