let v be a vector from intial p1=(-11,-12) to terminal point p2(2,5) write v in terms of i and j

jimthompson5910 (jim_thompson5910):

first compute p2 - p1 and tell me what you get

13, 17

jimthompson5910 (jim_thompson5910):

so the vector is 13i + 17j

jimthompson5910 (jim_thompson5910):

the 13i tells you to go 13 units to the right the 17j tells you to go 17 units up
