Q: If w = -4 + 3i, plot on the complex plane the point symmetric to w with respect to
a) the origin
b) the line with equation y = x


How do i do this question. I don't understand. Thank you.

This comes from fitzpatrick.
the solution is here

symmetric about the origin, is like the opposite side of the origin (4-3i)
symmetric about the line y=x. draw the line y =x, and then place the point opposite to that, on the line y =x (3-4i)

meh.. im bad at explaining

I still don't understand the 'symmetric about y=x' part :S

oooh i get it. thank you.
