anonymous · Answer

the slope of 1 perpindicular line is the negative of the reciprocal of the slope of the other line.

since one of the 2 lines has a slope of -1/13 the other has to have a slope of 13

13? Not -13?

anonymous · Answer

no because you aren't just taking the reciprocal but you are taking the negative of that reciprocal

anonymous · Answer

When one line is perpendicular to the other, the gradien is -1/the gradient of the first, in this case , for a line perpendicular to one with slope -1/13 is -1/(-1/13), giving 13.

Okay that makes sense now thanks guys :D
