Does it matter which point you use for (x1, y1) or (x2. Y2)?
Yes! You have to choose correctly or it's all
wrong!
No! As long as your x and y coordinates line up
with each other vertically in the equation,
then you're good to go!

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
