Question

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?

Answer 1

Given:

7x-9y=-5

Required:

To calculate the slope

Step-by-step explanation:

Find the slope of line that is perpendicular to 7x-9y=-5

`m=(-9)/(7)`

Find the slope of the line that is parallel to 7x-9y=-5

`m=(7)/(9)`

Required answer:

`m=(-9)/(7)\text{ m=}(7)/(9)`
