What is the equation of the perpendicular bisector of a line segment whose slope is 4/5 and whose midpoint is (-4,9)

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .

might be the correct answer will be question number 2

can i see a photo of the question so i can you?
