Perpendicular line

Question

What is the equation of the line that passes through point (6,2) and is perpendicular?

Answer 1

If you mean perpendicular to the x axis, then the equation is x = 6

If you mean perpendicular to the y axis then the equation is y=2

If you mean perpendicular to another line, you need to specify the line, as there are an infinite number of possibilities

Answer 2

There is not enough information here to answer this problem - you need at least two points to find the perpendicular line equation.
