Pleas help me with this it's due before 2:00 today

1. what is the formula for finding the vertical distance between two points on a coordinate plane?

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.

Which statements are true about additional information for proving that the triangles are congruent check all that apply
