If two distinct lines in a system of linear equations are parallel, they a. have the same slope and an infinite number of solution. b. have different slope with one solution c. have the same slope ans no solution. d have different slopes with no solution

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.
