Find a vector determined by the two points in ai+bj form and then find its magnitude.
(-3,1) and (4,-2)
(4,7) and (0,5)
I have no idea where to start. All I know is that a=<1,0> and b=<0,1>
I think that I want to find the ordered pair/component form of the vector
1) which will be <7,-3>.
Do I find the magnitude of that vector? (Squrt(58))
I do not know what to do know. I get stuck here if the first part is correct and I am not sure if that is correct.
