Answer:
D. 7 +11i
Step-by-step explanation:
In many situations, you can treat "i" as though it were a variable. Collect terms in the usual way.
(2 +8i) -(-5-3i) = 2 +8i +5 +3i = (2+5) +(8+3)i
= 7 +11i
For this case we have that the generic equation of the line is given by:

Where,
m: slope of the line
b: intersection with the y axis.
Since the line is parallel to PQ, then the slopes are equal.
We have then:

On the other hand we have:

Substituting values we have:
Answer:
The equation of the line that is parallel to line PQ and that has the and intercept b = -3 is:
Answer:

Step-by-step explanation:
Given
