Example Question #1 : Graphing
The graph of 
To answer this question, we need to correctly identify where to plug in our given values and solve for 
Points on a graph are written in coordinate pairs. These pairs show the 
We must now plug in our
We can now begin to solve for 
Therefore, the value of 
Example Question #1 : How To Graph Complex Numbers
Point A represents a complex number. Its position is given by which of the following expressions?
Complex numbers can be represented on the coordinate plane by mapping the real part to the x-axis and the imaginary part to the y-axis. For example, the expression 
Here, we are given the graph and asked to write the corresponding expression.
Example Question #2 : How To Graph Complex Numbers
Which of the following graphs represents the expression 
Complex numbers cannot be represented on a coordinate plane.
Complex numbers can be represented on the coordinate plane by mapping the real part to the x-axis and the imaginary part to the y-axis. For example, the expression 
Here, we are given the complex number 
Example Question #1 : How To Graph Complex Numbers
The point 
Because points on a graph are written in the form of 
In order to solve for 
We then solve the equation by finding the value of the right side, then dividing the entire equation by 5, as follows:
Therefore, the value of
