Answer: Since the exercise is incomplete, I'll give you the general steps to find the equation of the perpendicular bisector of PQ (See explanation).

Explanation:

1. You need to find the midpoint of PQ with the following formula:


M=((x_1+x_2)/(2),(y_1+y_2)/(2))

2. Then, you must find the slope of PQ with this formula:


m=(y_2-y_1)/(x_2-x_1)

3. By definition, the slopes of perpendicular lines are negative reciprocals. Knowing that, determine the slope of of the perpendicular bisector.

4. Remember that the Slope-Intercept form of a line is:


y=mx+b

Where "m" is the slope and "b" is the y-intercept.

Substitute the slope of the perpendicular bisector and the coordinates of the midpoint of PQ into the equation
y=mx+b.

5. Solve for "b".

6. Finally, substitute the values of "m" and "b" into
y=mx+b, in order to get the equation of the perpendicular bisector of PQ.
