Which graph shows the line joining the complex numbers -i and 2+!?
Artist 52 [7]

Answer:

D

Step-by-step explanation:

You are given two complex numbers -i and 2+i.

For the complex number z=x+iy, the ordered pair (x,y) represents this complex number on the coordinate plane.

So, the numbers:

  • -i=0-1\cdot i is represented by the ordered pair (0,-1)
  • 2+i=2+1\cdot i is represented by the ordered pair (2,1).

Plot these two points on the coordinate plane and coonect them with a straight line. You'll get the last option of graph.

Vera_Pavlovna [14]

Answer:
