Try this option:
way 1: using the picture, if x=-3 then y=-6.
way 2: the equation of this line is y=x-3; it means that y(-3)=-6.

Converting -4 to polar form gives $-4=4\exp(i\pi)$ .

Then the 4th roots of -4 would be the numbers

$4^{1/4}\exp\left(i\dfrac{\pi+2k\pi}4\right)$

where <em>k</em> is taken from {0, 1, 2, 3}.

So we have

$z_1=4^{1/4}\exp\left(\dfrac{i\pi}4\right)=\sqrt2\left(\cos\dfrac\pi4+i\sin\dfrac\pi4\right)=1+i$

$z_2=\sqrt2\left(\cos\dfrac{3\pi}4+i\sin\dfrac{3\pi}4\right)=-1+i$

$z_3=\sqrt2\left(\cos\dfrac{5\pi}4+i\sin\dfrac{5\pi}4\right)=-1-i$

$z_4=\sqrt2\left(\cos\dfrac{7\pi}4+i\sin\dfrac{7\pi}4\right)=1-i$
