Question

choose equation of a line perpendicular to the given equation and passing through the point p x-axis; P =(6,2)

Answer 1

To solve the question you have find the equation of the line that is perpendicular to the y axis and passes through the point (6,2), so in this case the equation of the line is y=2 as you can see in this picture

Remember that two lines are perpendicular when they form an 90 degrees angle between them
