The line y=3 is a vertical line. Thus, another line that is perpendicular to y=3 is a horizontal line. If this horiz. line passes thru the point (5, -6), then x = 5 is the desired equation.

Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y =
x - 6 ← is in slope- intercept form
with slope m = 
Parallel lines have equal slopes , then
y =
x + c ← is the partial equation
To find c substitute (9, 2) into the partial equation
2 = 6 + c ⇒ c = 2 - 6 = - 4
y =
x - 4 ← equation of parallel line
-------------------------------------------------------------------
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= -
, then
y = -
x + c ← is the partial equation
To find c substitute (9, 2) into the partial equation
2 = -
+ c ⇒ c = 2 +
= 
y = -
x +
← equation of perpendicular line
Just multiply my friend. The answer is 196
