Identify the equation in point-slope form for the perpendicular bisector of the segment with endpoints B(6,9) and C(8,−7).

Answers are one of the following

1.y − 1 = −8(x − 7)
2.y − 7 = 8(x − 1)
3.y−1=−18(x−7)
4.y−1=18(x−7)

is the equation in point-slope form for the perpendicular bisector of the segment with endpoints B(6,9) and C(8,−7).

Step-by-step explanation:

The endpoints:

Calculating the Midpoint M of BC:

The Midpoint M of BC

Calculating the slope of BC:

Given a line with slope then the slope of a

line  perpendicular to it is:
