Answer:
--- Slope intercept
--- Point slope
Step-by-step explanation:
Given
Perpendicular to
Required
Determine its equation
The general form of an equation is:
Where
By comparison:
Next, we calculate the slope of L.
Because L is perpendicular to , the relationship between their slopes is:
Substitute 4 for m
The equation of L in slope intercept form is:
Substitute -1/4 for m
In point slope form, we have:
Substitute -1/4 for m
