Question

Let v be the vector from initial point P1 to terminal point P2. Write v in terms of i and j

A. P1= (2,7), P2=(8,-5)

v=      i +       j

B. P1= (4,-4), P2= (4,-10)

v=       i+        j

 

Please do not help if you are not sure, trying my best to understand the material via different explanations in order to pass a class

Thank you! :)

Expert Solution
Step 1

A. we have two points p1(2,7) and p2(8,-5), the vector from p1p2 is 

v= (p2x-p1x)i + (p2y-p1y)j

   =(8-2)i +(-5-7)j

   = 6i - 12j
