Question

If gradient of line a is 4, what is the gradient of the line perpendicular to a

Answer 1

hope this correct -1/4...............

Answer 2

Since the gradient of a line (this slopeis found to be 4, line A. Any line that is I to another line will be the negative reciprocal of that slope. Line A's slope is , therefore, a line that is I to it will 4 have a slope of - 1/4 . m(1) * m * (2) = - 1 Answer is: - 1/4
