Question

a collection of points is shown on the complex plane.
which point represents the conjugate of z?
p
q
r
s

Explanation:

The complex conjugate of a complex number $z = a + bi$ is $\overline{z} = a - bi$. On the complex plane, this means the conjugate is the reflection of $z$ across the real axis (same real coordinate, opposite imaginary coordinate). Point $z$ is in the fourth quadrant; its reflection across the real axis is point $P$, which is in the first quadrant with the same real value and opposite imaginary value.

Answer:

P
