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:
- [tex]-i=0-1\cdot i[/tex] is represented by the ordered pair (0,-1)
- [tex]2+i=2+1\cdot i[/tex] 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.
