You can put this solution on YOUR website! Find an equation of the line satisfying the given conditions. Through (4,9); perpendicular
to 6x + 8y = 96
===============================
Step 1, find the slope of 6x + 8y = 96
The slope of lines perpendicular = -1/(slope of the line).
Call it m.
----
Step 2, use y-y1 = m*(x-x1) where (x1,y1) is the point (4,9)
