Consider the line .What is the slope of a line perpendicular to this line?What is the slope of a line parallel to this line?

Given:
7x-9y=-5
Required:
To calculate the slope
Explanation:
Find the slope of line that is perpendicular to 7x-9y=-5
[tex]m=\frac{-9}{7}[/tex]Find the slope of the line that is parallel to 7x-9y=-5
[tex]m=\frac{7}{9}[/tex]Required answer:
[tex]m=\frac{-9}{7}\text{ m=}\frac{7}{9}[/tex]
