no, but vertical lines have an equation of the form x = k , where k is a constantA line parallel to the axis Y can be a function?
Hello guys, i hv doubt in this question:
"1-Mark the point Q, such that the line through P (1, -2) and Q is perpendicular to the x axis (the horizontal axis) so that the point Q to point P is equidistant from the axis x. Find the equation of the line."
If the line be perpendicular of the X axis, so will be parallel of the Y axis. A line parallel to the axis Y can be a function?
OBS: Sorry about my bad technical English.
