Answer:
Slope of given line =
and slope of perpendicular line = 
Step-by-step explanation:
We are given a line -9x - 4y = 5 .
We have to find the slope of a line parallel to this line and also a line perpendicular to this line.
Let the general equation be ax + by = c.
Then the slope of this line =
= 
The slope of a line perpendicular to a line is the negative inverse of the slope of the line. Using this concept,
Slope of line perpendicular to the given line =
= 
1440 will be your least common multiple

REALLLYYY???!!!!!!
JK
thx 4 the points..
I think the answer is x= -7 +7/2y
