Answer:
A) 3y = x + 16
Step-by-step explanation:
The equation of a perpendicular line can be found by swapping the x- and y-coefficients and negating one of them. The constant will be chosen to match the given point.
Swapping coefficients, we get ...
-3y = x + c
Negating the y-coefficient gives ...
3y = x + c
Filling in the given point, we have ...
3(5) = -1 + c
16 = c
The equation of the perpendicular line can be written as ...
3y = x + 16 . . . . matches choice A
_____
Note that choice A is the only equation that gives a line with positive slope. The given equation has negative slope, so its perpendicular must have positive slope.

Answer:
The equation of the line is 
Step-by-step explanation:
step 1
Find the slope
The formula to calculate the slope between two points is equal to
we have
(-2,11) and (9,22)
substitute
step 2
Find the equation in slope intercept form
where
m is the slope
b is the y-intercept
we have
substitute in the equation and solve for b
Adds 2 both sides
The equation of the line is
