Consider the complex number on the complex plane and the complex number z2 = 6 – 3i. On a coordinate plane, the y-axis is labeled imaginary and the x-axis is labeled real. Point Z 1 is (2, 1).

When z1 and z2 are added together, the result moves z1 6 units _

and 3 units

.

The real part of z1 + z2 is _

.

The imaginary part of z1 + z2 is _

i.
