Answer:
Mid-point: 
Equation: 
Step-by-step explanation:
To find the mid-point of AB, simply add up their x and y coordinates and divide by 2 respectively to find their middle point.



To find the perpendicular slope that passes through the mid-point, we need to know the slope between AB first.
Slope of AB:
=
=
= 
Multiplying slopes that are perpendicular with each other always results in -1.


By the point slope form:

Plug in the coordinates of the mid-point:

Equation: 
Answer:
I think it's 88.
Step-by-step explanation:
4 x 11 = 44
8 × 11 = 88
