For this case we have that by definition, the equation of the line in the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
According to the figure, the line goes through the following points:
We found the slope:
By definition, if two lines are perpendicular then the product of their slopes is -1:
Thus, the equation is of the form:
If the line goes through we have:
Finally, the equation is:
Algebraically manipulating we have:
Answer:
Option A
