wait, it only 25 points...
Step-by-step explanation:
Answer:

Step-by-step explanation:
step 1
Find the slope of AB
we know that
The formula to calculate the slope between two points is equal to

we have
A(5,-1), B(9, -9)
substitute the values



step 2
Find the slope of the line that is perpendicular to AB
we know that
If two lines are perpendicular, their their slopes are opposite reciprocal (the product of their slopes is equal to -1)
we have

therefore
The slope of the perpendicular line is

step 3
Find the equation of the line in point slope form

we have


substitute

step 4
Convert to slope intercept form
Isolate the variable y
