Answer:
Explanation:
The equation of the line is given as
- 9x - 4y = 5
The slope intercept form of representing the equation of a line is expressed as
y = mx + c
Where m represents the slope
Rearranging the given equation in the slope intercept form, it becomes
4y = - 9x - 5
y = - 9x/4 - 5/4
The slope = - 9/4
If two lines are parallel, it means that they have the same slope. Therefore,
1) the slope of a parallel line to this line is - 9/4
2) if two lines are perpendicular, it means that the slope of one line is the negative reciprocal of the other line. Therefore,
The slope of a line perpendicular to this line is 4/9
