Question 1057306
 Find the equation of the line perpendicular to 
−2x + 9y = −5 passing through the point (−6, 11).
(Put the answer in y = mx + b form.) 
------
Rearrange the given equation::
y = (2x-5)/9
slope = 2/9
------
Every line perpendicular to it has slope -9/2
----------------------
y = mx + b
Substitute for x,y, and m ; solve for "b"::
11 = (-9/2)(-6) + b
11 = 27 + b
b = -16
----
Ans: y = (-9/2)x - 16
