Answer:
Step-by-step explanation:
Given
Perpendicular to
Required
Determine the line equation
An equation has the form
Where
By comparison with
Because the line is perpendicular to , the following relationship exists
i.e. the condition for perpendicularity
Where m1 is the slope of the equation that passes through
So, we have:
The line equation is then calculated using:
Where
So, we have:
Add 11 to both sides
