Find the magnitude of the vector
= (-3, 4).

we cant find the magnitude with just two coordinations.if that equation is y=mxand we can think that these is also a cordintion (0,0)..because line cross the middle of the chart.then we can use the equation m= y difference/x difference

m=(4-0)(-3-0 )

m=4/(-3)

m=-1.333

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
