If the product of 2 numbers is one, than those 2 numbers are recipricals

perpendicular fractions are gradients and are negative recipricals of each other and that multiply to give -1 for example:2/1 times -1/2 gives -1
Yes.
If you have two lines that have negative recipricals (1 and -1 for example), the lines are perpendicular.

They are the negative reciprocal of each other. Fo rexample, if a line has slope = +2, then the line perpendicular to it has slope -1/2

y=2x+3 and y =2x+5 (parallel because they have the same slope) y=2x+3 and y=(-1/2)x+5 (perpendicular because the slopes are opposite recipricals)
