Question 63489
When we draw the complex number i as a point in the complex plane, its coordinates are 
a. (0, i ) 
b. (1,0) 
c. (0,1) 
d. The number i cannot be drawn as a point in the complex plane 
Ans: (0,1) because the verticle axis becomes the imaginary part of the
comples number 0+1i.
-------------------------------
When we add the two complex numbers a + bi and c + di by representing them as points in the complex plane, then the sum is represented by 
a. The corner of a rectangle whose other three corners are (0,0), (a,b), and (c,d) 
b. The corner of a triangle whose other two corners are (a,b) and (c,d) 
c. the corner of a parallelogram whose other three corners are (0,0), (a,b), and (c,d) 
d. None of the above
Ans: the corner of a parallelogram etc.......
-------------------------
 
Just like we do for the real numbers, we can draw a picture of the complex numbers simply by drawing a line. 
a. True 
b. False
Ans: False ; you need a plane with a Real number line as horizontal axis
and imaginary numbers as the vertical axis.
