Question 436649: Find the sum of the complex numbers negative 4 + i and 2 + 3i. Express your answer in a + bi form and then plot the result on the graph that is given.
When I added them up I got negative 2 + 4i. Do I just plot this onto a graph and is this the correct answer? Thanks Gail

-----------------
-4+i + 2+3i = -2+4i
---
Plot this as (-2,4) on an x/y coordinate system.
==================================================
Draw a ray from (0,0) to (-2,4) if you are looking
for the sum (or resultant) of -4+i and 2+3i.
