Add 3+ 4i and 4+2i graphically
My class got 1+ 2 radical 10 /2 and 12 radical 10 /2 . whenever i put this into the y= graph, nothing shows up on the graph. Can someone tell me how to solve this algebraically and graphically?

add the real and imaginary parts separately:
3+4i + 4+2i = (34)+(4+2)i = 1 + 6i
on a graph, draw a line 3 units right, 4 units up to (3,4)
From there, draw a line 14 units left and two up to (1,6)
