Hello,
I had this problem to solve:
Find the equation of the perpendicular to the line y = 3 and passing through the point (4, 5).
I was baffled when I saw the question, because I can't make head or tail of it.
Thanks for your help!

- As I understand it, the line for an y = a equation is a horizontal line (slope zero).
- Therefore, a perpendicular line must be a vertical line (undefined slope).
- If a line is vertical, the value is just x = b, but it does not cross y, unless it is x = 0, in which case it coincides with y.
Thanks for your help!
