Find the equation of the right bisecter of the line segment joing the points (3,4) and (-1,2)
Step 1: Find the midpoint
Midpoint = ((3 + (−1))/2, (4 + 2)/2)
= (1, 3)
Step 2: Find the slope of AB
Slope of AB = (4 − 2)/(3 − (−1))
= 2/4 = 1/2
The perpendicular bisector has slope: −2
Step 3: Equation of the perpendicular bisector
Using point-slope form: y − 3 = −2(x − 1)
y − 3 = −2x + 2
Therefore,
2x + y − 5 = 0
The equation of the right (perpendicular) bisector is 2x + y − 5 = 0.
