Question

Find the slope of a line that is a) parallel and b) perpendicular to the given line.


9x−4y=1
slope of a parallel line-

slope of a perpendicular line-

Answer 1

slope of parallel line is same as that of the line i.e. 9/4

slope of perpendicular line is (-1/(9/4))=(-4/9)

Answer 2

Answer:

Step-by-step explanation:

the slope of the line 9x - 4y = 1 is

9 / 4.

if a line L is parallel to the line

9x - 4y = 1, then L has the same slope as 9x - 4y = 1, that is, 9 / 4.

if a line L is perpendicular to the line

9y - 4x = 1, then the slope of L is

- 1 / (9 / 4), that is, - 4 / 9.
