Answer:
44x +56y = 95
Step-by-step explanation:
To write the equation of the perpendicular bisector, we need to know the midpoint and we need to know the differences of the coordinates.
The midpoint is the average of the coordinate values:
((-2.5, -2) +(3, 5))/2 = (0.5, 3)/2 = (0.25, 1.5) = (h, k)
The differences of the coordinates are ...
(3, 5) -(-2.5, -2) = (3 -(-2.5), 5 -(-2)) = (5.5, 7) = (Δx, Δy)
Then the perpendicular bisector equation can be written ...
Δx(x -h) +Δy(y -k) = 0
5.5(x -0.25) +7(y -1.5) = 0
5.5x -1.375 +7y -10.5 = 0
Multiplying by 8 and subtracting the constant, we get ...
44x +56y = 95 . . . . equation of the perpendicular bisector
Answer:r=7/7744
move all terms to the left:
(7/22)(44)-(2r)=0
add all the numbers together, and all the variables
-2r+(+7/22)44=0
multiply parentheses
-2r+7/22*44=0
multiply all the terms by the denominator
-2r*22*44+7=0
multiply elements
-1936r*4+7=0
multiply elements
-7744r+7=0
move all terms containing r to the left, all other terms to the right
-7744r=-7
r=-7/-7744
