what is the equation for the perpendicular bisector of the line segment whose endpoints are (7,2) (1,6)

julia
The formula is yy1= m*(xx1)
1. Find the midpoint= [(x1x2)/2, (y1y2)/2]
you will get (4,2)
2. Find slope m1= [2(6)]/[7(1)]= 8/6=4/3
3. find the slope of the perpendicular line
m1*m2=1
4/3*m2= 1
m2= 3/4
4. Plug in given points (7,2) and (1,6) and m2 in the formula that I wrote in the beginning
y(2)=3/4(x(4))
y+2=3/4(x+4)
y+2=3/4x+3
y=3/4x+1 this is the equation your were looking for.
Please, make sure the numbers are correct and double check the math (in case of typo), but the actual idea is correct.
