Answer:
Step-by-step explanation:
Let
we know that
The perpendicular bisector pass through the midpoint of AB
step 1
Find the midpoint AB
step 2
Find the slope of the given line AB
The formula to calculate the slope between two points is equal to
substitute
step 3
Find the slope of the perpendicular bisector
we know that
If two lines are perpendicular, then the product of their slopes is equal to -1
we have
----> slope of the given line
substitute in the formula
step 4
Find the equation of the perpendicular bisector
we know that
The equation of the line into point slope form is equal to
we have
substitute
