$\renewcommand{\Im}{\operatorname{Im}}$
For question 4 in section 1.2, describe locus of points $z$ satisfying the given equation $\Im(2iz) = 7$. I ended up with something like $\Im(2ix2y) = 7$. So, $2x = 7$. Would that mean that it is a point at $x = 7/2$?
Is $x=c$ a point on $\mathbb{C}$? V.I.

$\{x+iy\colon x=c\}$ is not a point the plane, it is a set of points (a vertical line).
